What's your heart rate? Atrial fibrillation?

The heart rate is usually 60-200 beats per minute.

If the patient has a disease in the atrioventricular node, causing obvious atrioventricular block, the heart rate is generally lower than 60 beats per minute. However, if the patient has no disease in the atrioventricular node, its conduction function is normal, and the heart rate is usually greater than 100 beats per minute. If the patient has pre-excitation syndrome, the heart function is greatly affected, and the heart rate reaches 200 beats per minute or more.

The patient should follow the advice of the medical staff and take calcium channel antagonists, digitalis drugs, beta blockers, etc., which can alleviate cardiac dysfunction.
