Palpitation may be caused by physiological factors, generally do not need to take medication, may also be caused by pathological factors, such as arrhythmia, hyperthyroidism, etc., can follow the doctor’s instructions to apply drugs such as metoprolol, propafenone, amiodarone, propylthiouracil, mercaptoimidazole, etc., and there is no such thing as a potent drug, to be analyzed on a case-by-case basis. 1. Physiological factors: some patients may be due to exercise, emotional excitement, fatigue and other factors, causing increased sympathetic excitability, palpitation symptoms, generally do not need medication, palpitation can be relieved after the elimination of the above factors. 2. Pathologic factors: (1) Arrhythmia: due to the abnormality of cardiac pacing point or the blockage and interference of cardiac electricity in the process of conduction, causing arrhythmia and palpitation symptoms, if sinus tachycardia, atrial premature beats, ventricular premature beats can be given orally metoprolol, bisoprolol and so on according to the doctor’s advice; paroxysmal supraventricular tachycardia can be applied with propafenone, amiodarone and so on according to the doctor’s advice. (2) Hyperthyroidism: Due to thyroid tumor, hyperplasia, inflammation and other factors, the thyroid gland secretes too much thyroxine, which increases the basal metabolic rate of the body, causing the heart rate to accelerate, the cardiac muscle contraction force to increase, and the symptoms of palpitation appear, and the oral propylthiouracil, methimazole and so on can be given according to the prescription, and part of the patients may need surgical treatment. When palpitations occur, patients should go to the hospital in time to improve the electrocardiogram or 24-hour electrocardiogram, to clarify the causes of palpitations, according to the doctor’s instructions for treatment.
