A heart rate of 147 beats/minute is not normal; the normal heart rate is sinus rhythm, 60-100 beats/minute. If it is sinus rhythm, more than 100 times / min, called sinus tachycardia, the cause is usually divided into physiological factors and pathological factors. Physiologic factors are usually physical activity, emotional excitement, full meals, drinking strong coffee, etc., and do not require special treatment. After adjusting the above factors, the heart rate can return to normal, if it can not be restored for a long time, it is recommended to consult the hospital for further treatment.

If non-sinus rhythm, the presence of non-paroxysmal atrioventricular junction zone tachycardia, ventricular tachycardia, atrial fibrillation, atrial tachycardia, etc., the heart rate can reach 147 beats / min, according to the specific clinical situation, to take different treatments.
