One opinion circulating online is that "the number of beats of the heart is limited, between 2.5 billion and 3 billion times in a person's lifetime, so people with fast heartbeats may run out of heartbeats earlier and thus live a shorter life." Is this true?

The relationship between heartbeat and longevity
Normal resting heart rate (i.e., heart rate at rest) varies from person to person and is usually between 60 and 100 beats per minute. A lower heart rate may mean that the heart is pumping more efficiently each time and that the heart muscle is in better health. Indeed, some studies suggest that people with a lower resting heart rate may have a longer life expectancy than those with a higher heart rate. However, this doesn't mean that simply lowering your heart rate will prolong your life.
Heart rate and health
Heart rate is an important health indicator that reflects the health of the cardiovascular system. A high heart rate can be a sign of a variety of health problems, such as high blood pressure, heart disease, hyperthyroidism, etc.
Lifestyle influences
A healthy lifestyle, such as regular physical activity, a balanced diet, weight control, and stress management, can help maintain a healthy heart rate.
The association between heart rate and lifespan
While lower heart rates may be associated with longer lifespans, the relationship is not linear and is not causal. Heart rate is the result of a combination of factors, including genetics, health status, age, and more.
Individual differences
Heart rates vary greatly from individual to individual and are influenced by factors such as genetics, health status, physical activity level, and more. As a result, an "ideal" heart rate range can vary from person to person.
Exercise moderately
Moderate physical activity can increase the efficiency of the heart and help lower the resting heart rate in the long run.

There were 3 abnormalities in the heartbeat
or myocardial infarction, a sign of sudden death
Heartbeat is one of the important vital signs of the human body, and usually, the rhythm and frequency of heartbeat should be smooth and regular. However, in some cases, the heartbeat may be abnormal, which can be a sign of certain health problems, especially heart disease, including the risk of myocardial infarction and sudden death. Here are three abnormal heartbeat signals that may indicate the risk of heart attack or sudden death:
Rapid heartbeat
A sudden onset of rapid heartbeat, especially if there is no obvious cause, can be a sign of an arrhythmia. Arrhythmias are problems with the heart's beating rhythm or rhythm that can lead to a lack of blood flow, which increases the risk of myocardial infarction.
The heartbeat is unusually strong
A strong heartbeat or a feeling that the heart is "skipping," which is an irregular interval between heartbeats, can be a sign of a ventricular arrhythmia. A ventricular arrhythmia is a type of ventricular fibrillation or ventricular tachycardia, in which the rhythm and force of the heart beats can become very irregular, and in severe cases, it can lead to syncope and sudden death.
Slow heartbeat
Although a slow heartbeat is not necessarily directly associated with a heart attack or sudden death, certain conditions, such as bradycardia (heart rate below 60 beats per minute), can slow blood flow and affect the supply of oxygen and nutrients, which can increase the risk of heart disease.
It is important to note that the abnormal heartbeat signals described above are not specific, which means that these symptoms may not only be related to heart problems, but may also be a sign of other health problems. Therefore, if you experience any abnormal heartbeat, especially if accompanied by other symptoms such as chest pain, difficulty breathing, syncope, etc., you should seek medical attention immediately.

If your heart rate is lower than 60, you should be alert to five diseases
Heart disease
Bradycardia can be a sign of certain heart conditions, such as myocarditis, myocardial infarction (heart attack), heart valve disease, cardiomyopathy (a condition in which the heart muscle is damaged and fibrosis), etc.
Conduction system problems
The heart's conduction system is responsible for transmitting heartbeat signals from the heart's electrophysiological center to the heart's muscles. If there is a problem with the conduction system, such as an abnormality in the heart's sinus node or atrioventricular node, bradycardia can occur.
Hypothyroidism
Hormones secreted by the thyroid gland have an important impact on heart function. Hypothyroidism (low thyroidism) can cause a decrease in heart rate.
Medication side effects
Certain medications, such as β-blockers, antiarrhythmics, certain antibiotics and chemotherapy drugs, can slow the heart rate.
Electrolyte imbalance
Electrolytes such as potassium, magnesium, and calcium play a key role in maintaining normal heart function. An electrolyte imbalance can affect the heart's electrical signals, leading to bradycardia.
If symptoms of bradycardia, such as fatigue, dizziness, syncope, palpitations, or chest pain, seek immediate medical attention. Your doctor may recommend an electrocardiogram (ECG), exercise tests, blood tests (including thyroid function and electrolyte levels) and other relevant tests to determine the cause of bradycardia and provide appropriate treatment.
In some cases, if bradycardia is causing symptoms or problems with the heart's conduction system, a pacemaker may be needed to help regulate the heart rate.
