Sudden acceleration of heartbeat, long duration and numbness of hands and feet may be caused by physiological factors such as mental stimulation, which can be relieved by adjusting the emotions; it may also be caused by pathological factors such as various types of tachycardia and myocardial ischemia, which should be treated with appropriate medications such as metoprolol, nitroglycerin, etc., according to the cause of the disease, and interventional or surgical treatments should be carried out if necessary. 1. Physiological factors: such as mental stimulation, overwork, etc., no special treatment is needed, which can be gradually relieved by keeping calm, deep breathing and slow exhalation, and proper rest. 2. Pathologic factors: (1) All kinds of tachycardia: such as paroxysmal supraventricular tachycardia, rapid atrial fibrillation, etc. According to the specific conditions, choose propranolol, deacetyl furfuracein and other drugs to control the heart rate, and actively control the underlying diseases; if necessary, feasible catheter ablation. The use of medication should follow the doctor’s instructions, and should pay attention to the side effects of bradycardia, dizziness, gastrointestinal discomfort, blurred vision and so on. (2) Myocardial ischemia: use nitroglycerin to dilate coronary artery during acute attack; use metoprolol, isosorbide mononitrate, nifedipine, etc. to improve myocardial ischemia after the condition is stabilized, and use aspirin and atorvastatin to prevent myocardial infarction; if the condition is serious, consider coronary angiography, and perform percutaneous coronary artery intervention or coronary bypass grafting if necessary. The above drugs should be used according to the doctor’s prescription, and pay attention to the side effects such as headache, bradycardia, gastrointestinal discomfort, myalgia and so on during the use of drugs. If physiological factors are excluded, it is recommended to consult a doctor in time to identify the specific cause of the disease and treat it actively in order to avoid delaying the condition.
