Patients with arrhythmias and no organic heart disease can be cured by self-regulation if they show no symptoms. Symptomatic patients can be treated with drugs, catheter-based radiofrequency ablation, electrical cardioversion, or surgery. Arrhythmia is characterized by abnormal rhythm and frequency of the heart, which can be clinically classified as premature beats, ectopic tachycardia, atrial flutter and atrial fibrillation, ventricular flutter and ventricular fibrillation, and atrioventricular block. 1. Premature beats: it is the most common arrhythmia in clinic, and asymptomatic premature beats without organic heart disease can be left untreated. 2. Ectopic tachycardia or premature beats: they can be treated by drugs such as metoprolol, propafenone, amiodarone, etc. or catheter radiofrequency ablation. 3. Atrial flutter and atrial fibrillation, ventricular flutter and ventricular fibrillation: the treatment is more complicated, when the attack needs to be immediately given to the DC resuscitation, ventricular flutter and ventricular fibrillation also need to carry out cardiopulmonary resuscitation, the use of drugs such as propafenone, amiodarone, propranolol, etc. and catheter ablation, and the patient can be installed with buried automatic cardioverter-defibrillator (ICD). 4. Atrioventricular block: one degree of atrioventricular block generally does not require treatment, the second and third degree of atrioventricular block patients can be treated by treating the primary disease, the use of atropine, dobutamine and other drugs or artificial pacing. When the symptoms of arrhythmia patients are obvious, they need to go to the hospital in time and follow the doctor’s instructions for treatment.
