If it is accompanied by an increase in blood pressure, a series of antihypertensive drugs can be taken. If the tachycardia is accompanied by tachycardia, you can take metoprolol and other rhythm control drugs. In addition, a slow heart rhythm can also cause palpitations, and medications to increase the heart rhythm can be taken. If sudden palpitations are caused by neuroregulatory factors, a series of neuroregulatory Chinese medicines can be taken. The specific medication should be combined with the clinical situation and guided by the doctor’s consultation.
