Is a heart rate of 99 normal?

People of different ages generally have different heartbeats, and if their emotions fluctuate too much or they are exercising, their heartbeats will also be different. There are many reasons that affect the different heartbeats, but if the normal heartbeat exceeds or is not within the minimum normal range and it happens frequently, it is best to go to the hospital for relevant examinations and then actively receive treatment.

Is a heart rate of 99 normal?

The heart rate is 99 beats per minute, which is a normal heart rate, because the normal range of heart rate is 60-90 beats per minute. But in fact, the average heart rate of most people in intermittent state is 60-70 beats/minute. During normal daily activities, most people breathe around 70 to 80 times per minute. So if your heart rate occasionally reaches 99 beats/minute, it is normal. But if the heart rate exceeds 90 beats per minute during intermittent exercise and in daily life, it is considered to be a relatively fast heart rate. It is possible that the individual's physical constitution causes this relatively fast heart rate. On the other hand, it may be caused by other reasons, such as anemia, hyperthyroidism, etc., which can all lead to a relatively fast heart rate.

What causes an irregular heartbeat?

Negative emotions can cause cardiac arrhythmia, which can be fatal

Negative emotions are the cause of arrhythmia. A recent study shows that the electrocardiogram of arrhythmia caused by anger is more chaotic and unstable than general arrhythmia, so it is the most deadly.

Acid-base imbalance

If the electrolyte or acid-base balance in the body is disturbed, it may also cause arrhythmia. Severe hypokalemia can cause ventricular arrhythmias and lead to ventricular fibrillation. Severe acidosis can directly inhibit the myocardium, causing weak contraction and reduced responsiveness to catecholamines, leading to cardiac arrest. Severe hypertension and hypocalcemia can weaken myocardial contractility, produce intraventricular conduction block and lead to cardiac arrest. This cause of arrhythmia is relatively common.

Various organic heart diseases

Such as congenital heart disease, coronary heart disease, valvular heart disease, myocarditis, pericarditis, cardiomyopathy, endocarditis, etc., because the heart's sinoatrial node and conduction system are affected by the lesions, arrhythmias are very likely to occur, so arrhythmias are seen in almost all types of heart disease.

The electrical signals of the heart beat are delayed or blocked

Arrhythmias occur when the electrical signals that control the heart's beat are delayed or blocked. If this happens, on the one hand, it may be that the special nerve cells that generate cardiac electrical signals are not working properly, and on the other hand, it may be that the cardiac electrical signals cannot be transmitted normally in the heart.

Personal life

In fact, normal people may also experience arrhythmia. If they are overly tired, drink strong tea, or are stimulated by cigarettes and alcohol, or have large emotional fluctuations, other physical or mental stimulations can cause arrhythmia. Generally speaking, this arrhythmia is not dangerous, but it should still be treated with caution to avoid excessive damage to the heart. This is also a cause of arrhythmia.

Systemic or other systemic diseases

For example, diseases of the nervous system, endocrine system, metabolic diseases, trauma, surgery, cardiac catheterization, etc. can all cause arrhythmias.

Drug effects

Taking certain drugs can affect heart contraction and cause arrhythmia. In addition, sleeping pill poisoning can also cause serious arrhythmias. This is one of the causes of arrhythmia.
