Ventricular tachycardia in the elderly

Ventricular tachycardia (Ventricular tachycardia, VT) refers to the tachyarrhythmias of the bundle branches, myocardial conduction fibers, and ventricular muscles that occur below the bifurcation of the His bundle. Three or more consecutive spontaneous ventricular depolarizations, including monomorphic non-persistent and persistent ventricular tachycardia and polymorphic ventricular tachycardia. If it is ventricular tachycardia induced by programmed cardiac electrical stimulation during cardiac electrophysiological examination, it must be 6 or more rapid ventricular beats (frequency: 100 beats / min). Ventricular tachycardia can originate from the left ventricle and the right ventricle. Frequent episodes of frequent tachycardia often exceed 100 beats / min, and can deteriorate the hemodynamic state, which may degenerate into ventricular flutter and ventricular fibrillation, leading to cardiac origin Sudden death requires active treatment.
