Ventricular tachycardia is a more serious arrhythmia, which can be terminated by drugs when it occurs. If combined with hemodynamic instability, immediate electrical cardioversion is required to terminate the tachycardia attack; if idiopathic ventricular tachycardia, branch folding ventricular tachycardia or scarring ventricular tachycardia occurs, it should be eradicated by radiofrequency ablation surgery after the stabilization period. If after radiofrequency ablation, combined organic heart disease, such as combined ventricular tachycardia, terminate ventricular tachycardia at the same time, pay attention to the treatment of the original disease, such as the recurrence of combined organic heart disease after the removal of the causative factors, late ICD implantation to prevent sudden death.
