Continuous premature beats tachycardia, should improve the 24-hour dynamic electrocardiogram, cardiac ultrasound and other examinations before considering drug treatment or radiofrequency ablation treatment. Tachycardia due to premature beats is defined as 3 or more consecutive premature beats, which should be actively treated with medication. Without timely intervention, tachyarrhythmia may lead to acute heart failure or cardiac arrest. 24-hour ambulatory electrocardiogram, cardiac ultrasound and, if necessary, coronary angiography and myocardial nuclear magnetic resonance imaging should be performed as soon as possible to clarify the number, type and etiology of premature ventricular beats and ventricular tachycardia. If the cumulative number of premature beats is found to be less than 10,000 or less, it can be treated with oral antiarrhythmic drugs, metoprolol tartrate, propafenone hydrochloride, amiodarone. Frequent premature beats, idiopathic ventricular tachycardia, and monomorphic ventricular tachycardia can be treated with radiofrequency ablation if the cumulative number of premature beats is found to be greater than 10,000 or more. If there is a combination of organic heart disease such as coronary artery disease, the need for ICD implantation will be evaluated based on the treatment of the primary heart disease. Premature tachycardia should be treated promptly and according to medical advice.
