A woman's heart beats faster than a man's. Male and female heart

Text: Ekaterina Eliseeva

On the eve of March 8, the site thought: are we really beings from different planets or are the rumors that men are fundamentally different from women greatly exaggerated.

Let's leave out the obvious things like gender and talk about more interesting physiological differences that may also be of some practical use.

Information about Adam's rib has not been confirmed, but still, there are enough differences between us ...

Women freeze faster

This difference can become another strong argument “for” getting a new fur coat (so what, spring is starting) or a jacket. We get cold because we have fewer muscles that the body needs to produce heat.

Women have more developed hearing and sense of smell

The reason for the appearance of these features is the need to raise children. Mom, even in a dream, is able to hear the slightest changes in the baby’s breathing and wake up from this, while dad will not pay any attention to these nuances. A subtle scent protects us and the offspring that depends on us from eating spoiled foods. Why not say “Thank you” to evolution and buy another bottle of perfume, since it happened so?

Women are more sensitive

In those areas of the brain that are responsible for feelings, women have 10% more nerve cells. By the way, in those areas that are in charge of memory, we have a head start of the same 10%. Our left and right hemispheres are much better connected than men's. Therefore, men are still proud of Caesar, who could do several things at once, and we consider the ability to talk, cook, think about something of our own and at the same time check the lessons of the child for granted. Our gray cells differ from men's also in weight. But talking about the fact that the male brain weighs about 14% more than the female one is not at all necessary - after all, ours functions better!

Women breathe deeper

Our lungs are somewhat smaller than men's (and our bodies are also smaller). But due to the fact that we breathe deeper, with each breath we "manage" to get the same volume of air as men (about 0.5 liters at rest). Thus, despite this difference, we supply the body with a large amount of oxygen. Rising and falling female breast- a spectacle that fascinates men. You can buy another nice bra - balconette or push-up, to once again be convinced of this.

Women's heart beats faster

Our heart is smaller than a man's, so it's "programmed" to beat faster to make up for that difference. At rest, this is about 80 beats per minute (for comparison, men have an average of 72 beats). The fact is that in the female body circulates 3.6 liters of blood, almost a liter less than in men (4.5 liters). An accelerated heart rate is closely related to deep breathing - this way the body gets enough oxygen. Thanks to this combination, our body can also cope with more serious tasks, such as providing oxygen to both mother and fetus during pregnancy, when the amount of circulating blood increases by about 1.5 liters.

As you know, any woman is a mystery, but scientific research still allows you to learn a lot about female physiology. Some of the discoveries are shocking.

Good immunity

It is wrong to call the female gender weak, since the immunity of women is better than that of men. According to Ghent University researchers, two X chromosomes mean women have more microRNA, which boosts the immune system and reduces the risk of cancer.

In addition, according to Maya Saleh, MD, from McGill University, the hormone estrogen inhibits the inflammatory process. Developed immunity also slows down aging - women are known to live longer.

female brain

Danish scientist Bert Pakkenberg found that there are four million more cells in the male brain, but women perform 3% better than men in tests.

The corpus callosum, which serves as a kind of “cable” between the right and left hemispheres of the brain, is thicker in women than in men, and there are 30% more connections in it. Therefore, a woman at home can do many things, for example, cook, take care of children, take care of relatives, and so on, while a man is “imprisoned” for one thing.

female sense of smell

In terms of smell, women have no equal. A woman's nose can catch not only the smell of burning that threatens the house, but also the smell of pheromones, which cannot be done consciously. Moreover, a woman’s brain is able to “read” the smell of a man and decipher it, determining how strong his immunity is.

Scientists believe that in most cases a woman needs no more than three seconds for this.

Heart and receptors

A woman's heart beats faster than a man's. She also has more taste buds on her tongue. Women also have more pain receptors, but women's sensitivity to pain is higher than men's.

Color differentiation

On the retina of the human eye are almost seven million receptors, "cones", which are responsible for the perception of color. The X chromosome is responsible for their action. Women have two of them, and the palette of colors that they perceive is wider.

As the experiments of scientists from New York University showed, it is difficult for men to distinguish between the slightest shades of yellow, green and blue. In other words, if a man and a woman are shown an orange, then for the man it will be “more red”. It's the same with grass - it's always greener for women than it is for men.

According to Professor Israel Abramov, differences in the perception of color by different sexes cannot be explained by differences in the structure of the eye. The answer lies in how the brain, under the influence of the hormone testosterone, processes and perceives signals from the organs of vision. The researcher believes that such an ability could have been formed even before the advent of agriculture, when men were engaged in hunting, and women were gathering - searching for edible plants.

As a result, men are better at distinguishing small details of moving objects - a useful quality for hunters, and women are better at distinguishing colors.

peripheral vision

Women have well-developed peripheral vision. For some of them, it reaches 180º, and that is why women rarely miss side impacts when driving a car and can, without turning their heads, “count” an opponent or follow a child. The brain of a man provides tunnel vision, he "leads" the target and sees only what is in front of him, without being distracted by trifles.

Sensitivity

A woman's skin is 10 times more sensitive than a man's skin. Studies by British scientists have shown that even the most sensitive man in this sense falls short of the most insensitive woman.

Flexibility

Women are genetically more flexible than men. This is due to the reproductive function of women - their ligaments and muscles have more elastin than collagen. This happens because the female body produces much more of the substance hyaluranidase, which is responsible for the production of elastin.

Useful toxicosis

Scientists have found another explanation for female toxicosis during pregnancy. Professors Paul Sherman and Samuel Flexman of the University of Colorado said morning sickness and headaches are the result of a defense mechanism that protects the fetus from harmful toxins found in meat, fish and poultry. This explains the fact that toxicosis is a frequent occurrence in the early stages of pregnancy, when the fetus is most vulnerable. In addition, according to a study published in the Quantity Review of Biology, women who suffer from internal malaise have a much lower rate of miscarriage than others.

A woman's heart looks the same as a man's, but there are differences. For example, a woman's heart is often smaller (as are some of its internal chambers). And the walls that separate some of these chambers are thinner.

A woman's heart works faster, but pumps out 10% less blood with each beat than a man's. But when a woman is nervous, her pulse quickens - and the heart pumps more blood. As for male stress, the arteries in his heart constrict, raising his blood pressure.

Do such differences matter? How gender plays a role when it comes to symptoms, treatment, and outcome of heart disease.

Ischemic heart disease (CHD)

IHD is a common cause of a heart attack. An excess amount of lipids in the blood settles on the walls of the arteries of the heart, forming deposits - plaques. Accumulations of this kind grow, become hard - gradually narrow the arteries, preventing blood flow. This causes arteries to rupture and form a clot that blocks blood flow. The result is a heart attack.

6 differences in the symptoms of female and male coronary artery disease

1. Female risk factors. Some diseases that only affect women increase the risk of CHD: endometriosis, PCOS, gestational diabetes, and high blood pressure during pregnancy.
2. Men are more at risk of heart attack early age than women. Estrogen protects a woman's heart from disease, but after menopause, estrogen levels drop. Therefore, the average age of a heart attack in women is 70, and in men it is 66 years.
3. The symptoms of a heart attack in women are different from those in men. Pressive chest pain is the most common symptom of a heart attack in men. Some women also experience chest pain, but it is very common for symptoms to occur within three or four weeks before a heart attack, including:

• bouts of extreme fatigue
• shortness of breath and sweating
• back, neck or jaw pain.

1. IHD is difficult to diagnose in women. Angiography is the gold standard for detecting narrowing or blockage in the large arteries of the heart. But CAD in women often involves small arteries that may not be seen on angiography. That's why any woman who gets an "All right" conclusion after an angiography but continues to experience overt symptoms of coronary artery disease should see a cardiologist.

1. consequences of a heart attack. Women tolerate heart attacks worse and need rehabilitation longer. This may be due to the fact that women often prioritize the family and caring for it, rather than their own health. Therefore, many diseases are left without attention and the necessary treatment.
2. Adequate treatment after a heart attack. After a heart attack, women are at greater risk for blood clots, which can lead to another heart attack. Women are more likely than men to suffer from a second attack in the next 12 months.

Heart failure

Heart failure in men is usually caused by damage after a heart attack. And women are more likely to develop heart failure due to high blood pressure, chronic kidney disease, or other conditions that prevent the heart muscle from resting between beats. Women with this type of heart failure usually live longer than men with the same condition.

Atrial fibrillation

Atrial fibrillation (AF) causes the heart to beat irregularly and rapidly. Recent studies have shown that women with AF have more symptoms, a poorer quality of life, a higher chance of stroke, and more deaths. In addition, they are more likely to resort to catheter ablation. Despite these problems, women who do not neglect treatment for AF live longer and reduce their chances of death from heart disease, in contrast to men with AF.

Protect yourself

Regardless of gender, you need to do everything possible to reduce the likelihood of a heart attack:

• quit smoking
• exercise regularly (at least 30 minutes of physical activity per day)
• eat properly
• maintain normal weight, blood pressure and blood sugar levels.

Everyone knows that women and men differ from each other in many aspects. Some things can be seen with the naked eye, because they are clearly visible in everyday life. Differences in emotionality, communication, skills and interests are noticeable.

What is the difference between males and females?

The heart of a man and a woman

A woman's heart is different from a man's heart. A woman's heart is beating 72 times per minute and a man's heart only 65 times a minute. This is due to the smaller volume of women's hearts, by 10-15%, and less blood volume (the heart must beat faster to supply the entire body with oxygen).

Despite the fact that a woman's heart beats faster, in many cases it retains its effectiveness longer. Besides, women are naturally more resilient than men. Thanks to this, they cope much better with various diseases and problems.

Burning calories for men and women

Often there comes a moment in life when we want to lose a few pounds. Probably, each of the women has repeatedly wondered why her partner copes with the loss of extra pounds much faster.

Every day, men, even without exercise, just during the performance of daily duties, burn 50 more calories than women. This is because the percentage of body fat in a woman's body is about 20-28%, while in a man the norm is 14-20 percent.

This is due to differences in the structure of the body of a man and a woman, as well as the percentage of muscle mass., which is the main consumer of calories, in women, muscles make up 25-30%, and in men - 40-50 percent.

A large muscle mass in men is associated with the release of male hormones, that is, testosterone, which largely affects the growth of muscle mass. This is also affected by the percentage of water in the body - for women it is 45-60 percent, and for men - 50-65%.

Feelings of a woman and a man

Women are much better at distinguishing colors. All thanks to the innate sensitivity that is associated with the X chromosome.. In addition, they also have better hearing, which allows them to detect higher frequency sounds and smell better.

There are also differences in vision. Men see far better, but the field of view is limited. Women, on the other hand, are characterized by a wide field of vision aimed at the immediate environment.

Who is more sensitive

Men blink for centuries twice as rarely as women, who can cry from 30 to 65 times during the year (men only 6-17 times).

Men's skin is 10 times less sensitive than a woman's, in addition, a woman's body from birth has greater flexibility and plasticity.

Female hormones such as estrogen and progesterone cause their skin to tend to be warmer because these hormones increase the blood supply to the skin.

Skeleton design differences

The female skull differs from the male in 14 elements., for example, the thickness of the eyebrows, the angle of the forehead, as well as the appearance of the mandibular joint. That is why men have sharper facial features.

In addition, the skeleton of an adult woman weighs an average of 10 kg, and a male skeleton weighs about 12 kg. Even women's hair differs in construction from men's hair because its diameter is up to two times thinner.

Lies of a woman and a man

Interestingly, scientists confirm that women are much better at detecting lies, but can also skillfully lie and hide their lies.

According to research, women, however, most often lie for polite reasons, such as wanting to please someone, or fear of offending someone. And men, according to the study, are more likely to lie in order to present themselves in a better light and get some kind of benefit.

Women smile more

Women have an innate instinct to smile. Scientists confirm that this can be seen as early as the eighth week of their life.

In addition, from adolescence, the female sex shows more interest in other people. Because of this, they are much easier to read the emotional states of other people.

Medicine is well aware that the hearts of men and women are different. And they also get sick in a different manner. In this article, specialists in cardiology and cardiac surgery of the Embassy of Medicine talk about the features of cardiac arrhythmia in the male and female heart - about arrhythmias.

Why does this difference exist? There is no general opinion on this subject among specialists in cardiology and cardiac surgery. It is assumed that the reason lies in the action of different hormones in men and women on the ion channels of cell membranes and in the difference in the tone of the nerve endings involved in the work of the heart.

According to cardiology, a woman's heart beats faster than a man's by 3-5 beats per minute. The heart rate in women changes during different phases of the menstrual cycle. Women certainly have an exclusive on the development of sinus tachycardia, which is rare in men. And atrial fibrillation - the most common cardiac arrhythmia, men suffer 1.5 times more. This difference in the incidence of atrial fibrillation disappears only in the age group of people over 70 years of age.

Women are more likely to experience disorders in the repolarization of the cells of the heart - the process of restoring their ability to electrical activity after each heartbeat, which can manifest itself as clinical symptoms. These changes place women at a high risk of developing cardiovascular disease during menopause.

There is a significant difference in the incidence in men and women of such a severe and dangerous arrhythmia as ventricular tachycardia, and the sudden death caused by it. This disorder affects more men, and the ratio of cases of this arrhythmia between different sexes is 4:1.

According to experts in cardiology, there are significant differences in the effectiveness of various techniques for treating heart disease in men and women, such as antiarrhythmic drug therapy, or the use of defibrillators. Women always need more gentle medical intervention.

Cardiac arrhythmias appear due to a violation of the generation of electrical impulses or their conduction through the heart muscle. The heart has a real natural generator - the sinus node, which generates electrical impulses. They are transmitted to all cardiac fibers to organize coordinated contractions of their different groups.

Arrhythmias are characterized either by the appearance of self-proclaimed and defective rhythm generators, or by the destruction of the normal pathways for these electrical impulses, which causes the heart to begin to contract in an irregular and uncontrolled rhythm.

Diagnosing an arrhythmia is not an easy task. Often they are completely asymptomatic or in the form of short attacks, when it is impossible to do electrocardiography. Nevertheless, modern cardiology has a sufficient set of technical means to make a correct diagnosis if an arrhythmia is suspected. To do this, you just need to see a doctor.

Arrhythmias of arrhythmias are different. The most common heart complaint that patients present to a family medicine doctor is a complaint of a strong heartbeat - palpable heart pulsations. This symptom is usually associated not with a real pathology of the heart, but with other diseases or with the emotional state of the patient. Strong palpitations can appear after physical exertion, strong emotions, against the background of nervousness. A common cause of palpitations can be an attack of panic and anxiety, which is combined with a feeling of lack of air and constriction of the throat. Taking alcohol, tonics and some medications - antidepressants, bronchodilators and others also increases the heartbeat. In the same way, the pulse accelerates during fever or with anemia and thyrotoxicosis.

Usually the heart beats at a rate of 50-100 beats per minute, and this rhythm adapts to the situation in which the person is: it becomes faster when we are nervous or physically active.

Specialists in cardiology recommend consulting a family doctor if there are disturbances in the normal rhythm of heart contractions. In modern medicine, there is a wide range of medicines to choose the appropriate treatment in each case. Cardiac surgery has a radical method for the treatment of many artmias - the method of ablation through a catheter.
