Why Do I Feel My Heart Racing?

There are many reasons for feeling a rapid heartbeat, and the most common ones are psychological and emotional factors. For instance, being suddenly startled or experiencing adverse stimuli, or suffering from significant blows can all lead to excessive secretion of adrenal hormones, causing an accelerated heartbeat. It may also be related to heart disease or blood pressure issues, which can also cause such problems.

1. Being startled or experiencing external stimuli can lead to the secretion of adrenaline by the body, causing a physiological increase in heartbeat;

2. Abnormalities in the heart's conduction system, or pathological tachycardia caused by paroxysmal atrial fibrillation in hypertensive patients or the elderly;

3. Thyroid dysfunction. It could be caused by hyperthyroidism. Some people with hyperthyroidism often experience excitement of the sympathetic nervous system and an accelerated basal metabolic rate.

A rapid heartbeat is tachycardia, which generally exceeds 100 beats per minute. If tachycardia exceeds 180 beats per minute, it can lead to decreased cardiac output and insufficient blood supply in patients. Prolonged tachycardia can also lead to myocardial fatigue and angina pectoris. When experiencing a rapid heartbeat, it is necessary to identify the cause and use appropriate medication to control the heart rate. At the same time, it is important to relax and ease stress.
