What causes rapid heartbeat at night?

Most heart diseases are very dangerous, and when they occur, they may threaten the patient's life. Therefore, for heart patients, they must control their mood and not let themselves be overly excited. Moreover, our heartbeat frequency is different. The frequency is different when we get up early and go to bed at night. So what is the reason for a fast heartbeat at night?

It may be paroxysmal supraventricular tachycardia, which is a paroxysmal rapid and regular heart rhythm, abbreviated as "supraventricular tachycardia", which is relatively common. It is characterized by sudden onset and sudden cessation. During an attack, the patient feels his heart beating very fast, as if it is about to jump out, which is very uncomfortable. During an attack, the heart rate is 150 to 250 beats per minute and lasts for seconds, minutes, hours or days.

Sometimes when the doctor arrives, the patient's attack has already ended. Palpitations may be the only symptom, but if there is a history of coronary heart disease or other heart disease, dizziness, fatigue, difficulty breathing, angina pectoris, syncope, and electrocardiogram changes showing myocardial ischemia may occur and persist for 1 to 2 weeks after the tachycardia stops. Some patients are first diagnosed with coronary disease after developing supraventricular tachycardia. In addition to coronary heart disease, other causes of supraventricular tachycardia include hypertensive heart disease, cardiomyopathy, rheumatic heart disease combined with mitral stenosis, hyperthyroidism, and preexcitation syndrome. Some young people may also suffer from attacks even without having a heart disease.

If your heartbeat often suddenly speeds up and you feel anxious, you should consider whether you have arrhythmia such as sinus tachycardia, supraventricular tachycardia, atrial fibrillation, etc. Go to the hospital for an electrocardiogram and 24-hour dynamic electrocardiogram monitoring to determine the cause of the disease. Suggestions: You should go to the hospital for an electrocardiogram to check the basic situation. If necessary, a 24-hour dynamic electrocardiogram can be performed to observe the changes and fluctuations of the heartbeat during the day.
