Visibly feel the heart beating faster

As we all know, the heart is one of the five internal organs of the human body and plays an extremely important role. It can provide pressure for blood flow and promote blood flow to all parts of the body. The normal heart rate is 65-80 beats/minute. However, in situations such as strenuous exercise or high tension, the heart rate will increase. The editor will explain to you the seven specific reasons why the heart beats faster.

Seven reasons

1. There is a lot of pressure. Dr. Pam Taub, associate professor of medicine at the University of California, San Diego, believes that stress can cause the heart rate and blood pressure to increase, sending the body into "fight or flight" mode. Chronic stress can put the heart on high alert, increasing a person's likelihood of having a heart attack or stroke.

2. The heart's electrical conduction system is short-circuited. The heart has its own unique electrical conduction system, a network of signals that helps it beat properly, and a slow heart rate may indicate that something is wrong. If there is a problem with the electrical conduction system, people will feel top-heavy. By doing an electrocardiogram, the doctor can pinpoint the exact cause of the heart malfunction.

3. Not exercising enough. The principle of “use it or lose it” also applies to the heart. The heart is a muscle and it needs exercise to function properly. Inactivity and obesity can contribute to an elevated resting heart rate. Conversely, adequate exercise can help lower your resting heart rate. The resting heart rate of competitive athletes is usually less than 60 beats per minute.

4. Caffeine. On the other hand, caffeine can increase your heart rate for a short period of time. It's commonly found in headache medications and can also lurk in foods and drinks, such as chocolate and tea. Some people are highly sensitive to caffeine and their heart rate will increase immediately after consuming coffee or an energy drink.

5. Side effects of medication. Certain medications can reset heart rate readings, setting a new normal. Beta-blockers and calcium channel blockers are the main drugs that cause heart rate slowing. They both relax the heart and are generally not dangerous.

6. Water or drinking too much water. Drinking too much water or not enough water can cause an imbalance in the ratio of electrolytes to water in your system, disrupting the chemical reactions in your body. Low levels of potassium, calcium or magnesium can cause arrhythmias, which manifest as an increased heart rate. 7. Abnormal thyroid function. The hormones produced by the thyroid gland help the body function properly. If it doesn't produce enough hormones, you can develop hypothyroidism, which can cause your heart rate to slow. On the other hand, if the thyroid gland produces extra hormones, you develop hyperthyroidism, which can increase your heart rate. If you suspect you have a thyroid problem, just get a blood test. Do a good job in heart rate management and let patients understand the concept of healthy heart rate.

Every beat of a person's pulse represents an effective heartbeat, and the number of heart beats per minute is the heart rate. The normal heart rate of an adult at rest (resting heart rate) is 60-100 beats/minute. The total number of heart beats in a person's lifetime is about 2.5 billion to 3 billion times. If the resting heart rate is around 60 beats, the life expectancy can reach 93 years. The regularity of the heartbeat and the number of heartbeats affect human health, especially for patients with cardiovascular diseases. Resting heart rate is closely related to cardiovascular disease. Studies have confirmed that people with a faster heart rate at rest have higher systolic and diastolic blood pressure, and a faster heart rate also increases the risk of cardiovascular disease and death. It can be said that the faster the heart rate, the shorter the life span.

The relationship between heart rate and cardiovascular disease Experts say that an increased heart rate reflects the activity of the sympathetic nerves in the body. Sympathetic excitement will secrete a large amount of catecholamines such as adrenaline and norepinephrine. Under the action of these hormones, the heart rate increases, blood pressure rises, and breathing speeds up. When the sympathetic nerves remain active and the level of adrenaline secretion continues to rise significantly, the heart's consumption also increases.

Sympathetic nerve activity and hypertension are causally related. Experts point out that if the heart rate is too fast, the chance of developing high blood pressure is high, and conversely, high blood pressure can also cause damage to heart function.

Patients with hypertension need to manage their heart rate better. For patients who already have hypertension, inhibiting sympathetic nerve activity can slow down the heart rate and lower blood pressure. Studies have shown that chronic activation of neuroendocrine hormones plays an important role in the occurrence and development of cardiovascular diseases in the elderly. The central sympathetic nervous system tension increases in most elderly people, which is closely related to the occurrence of cardiovascular diseases. Therefore, it is particularly important to inhibit the increase in central sympathetic nerve activity in the elderly, while monitoring changes in cardiac function and the contraction amplitude of individual myocardial cells, to provide a theoretical basis for the prevention and treatment of cardiovascular diseases in the elderly.
