Ventricular premature contractions of more than 20,000 times may refer to ventricular premature contractions of more than 20,000 times/hour, and may also refer to ventricular premature contractions of more than 20,000 times/minute. The severity of ventricular premature contractions of 20,000 times/24 hours cannot be determined simply by the number of frequent contractions, but also by whether the contractions are single ventricular contractions or multiple ventricular contractions, such as duplex or triplex rhythm, and by whether the ventricular tachycardia is combined with heart disease. It also depends on the combination of ventricular tachycardia and heart disease. If the ventricular premature beats are more than 20,000 times/minute, it is considered as a serious condition.1. Usually not too serious: If the ventricular premature beats 20,000 times/24 hours are only occasional and not combined with typical heart diseases, and there are no symptoms such as chest tightness, shortness of breath and dyspnea, they can be controlled by medication and are usually not too serious. At this time, it mostly needs to be treated by drugs combined with lifestyle changes, such as the application of antiarrhythmic drugs like metoprolol and amiodarone hydrochloride as prescribed by the doctor to control the heart rate. At the same time, we should pay attention to rest, avoid overexertion, and avoid excessive emotional excitement, and we should also pay attention to avoid drinking strong tea, coffee, etc., which may cause the heart rate to accelerate, which is not conducive to the recovery of the disease; 2. relatively serious: if the ventricular premature beats 20,000 times/24 hours do not improve after removing the causative factors, it usually means that the ventricular premature beats belong to multiple lesions, such as duplex rhythm, triplex rhythm, etc., and This is usually a serious condition, which cannot be relieved by drugs alone and may require radiofrequency ablation surgery to eliminate the ectopic pacing points through the peripheral vasculature. After treatment, the patient’s vital signs need to be continuously monitored to prevent life-threatening heart rate abnormalities. However, premature ventricular contractions of more than 20,000 beats per minute are usually considered to be relatively severe and may be life-threatening if not treated actively. If there are too many premature ventricular beats, the danger is relatively high, especially transient and persistent ventricular tachycardia, which can easily cause ventricular fibrillation and induce sudden cardiac death if not actively treated. Once ventricular premature beats occur, patients should go to the hospital for treatment in a timely manner to avoid delaying the condition.
