Multiple source premature ventricular pacing is important and needs to be treated promptly. Polygenic premature ventricular beats are caused by premature impulses from multiple pacing points of the heart, and most of the patients will suffer from arrhythmia. These arrhythmias can be caused by coronary artery disease, abnormal sinus node function, rheumatic heart disease, etc. Depending on the cause of the disease, the degree of harm to the body varies greatly. Multiogenic premature ventricular contractions caused by abnormal electrical function of the heart can be treated with radiofrequency ablation surgery and other procedures under the guidance of a doctor, which can completely eradicate the disease. Those caused by coronary heart disease, rheumatic heart disease, etc. need to be treated for coronary heart disease, rheumatic heart disease and at the same time control the ventricular rate. The severity of the symptoms of this type of multifocal premature ventricular contractions depends mainly on the severity of coronary heart disease and rheumatic heart disease, and it is difficult to treat and not easy to cure. Multiple ventricular premature beats need to be taken seriously as they can easily be combined with more serious ventricular arrhythmias and become life-threatening, so they need to be treated in an active hospital setting.
