Fast pulse may be caused by physiological factors or heart disease or systemic disease. General treatment, medication and radiofrequency ablation can be taken to relieve the symptoms according to the cause of the disease. 1. Physiological factors: When the mood is tense, anxiety, irritability, it will lead to rapid heartbeat and rapid pulse rate. This situation does not require special treatment, and the pulse rate will return to normal after the emotion is relieved. 2. Heart disease: for example, coronary heart disease, myocardial infarction, etc. Such diseases may cause tachyarrhythmia, which will also affect the pulse, resulting in rapid pulse and rapid heartbeat. Oral nitroglycerin, isosorbide nitrate and other drugs can be prescribed, while oral amiodarone, propafenone and other treatments for arrhythmia, if necessary, radiofrequency ablation surgery. 3. Systemic diseases: for example, prolonged diarrhea, vomiting, resulting in water and electrolyte disorders, blood volume insufficiency, which will cause rapid pulse. Drinking more water or supplementing liquid salts should be done to prevent hydroelectrolyte disorders. Fast pulse needs to be tested regularly. If the pulse rate is more than 100 beats per minute and cannot return to normal after resting, you should consult a doctor in time and analyze the cause before treating the symptoms.
