  Ventricular tachycardia (VT) refers to tachyarrhythmias that occur in the fascicles, myocardial conduction fibers, and ventricular muscles below the bifurcation of the fascicles. According to BORSAM Biomedical,Wellens defines it as: frequency of more than 100 times/min, three or more consecutive spontaneous ventricular electrical activity, including the simplex non-durable and sustained ventricular tachycardia and polymorphic ventricular tachycardia, if is the heart in the cardiac electrophysiological examination induced by electrical stimulation of ventricular tachycardia, it must be the last six or more than six the quickness of ventricular beat frequency (> 100 times/min). Ventricular tachycardia can originate from the left ventricle and the right ventricle, and the frequency of continuous attack often exceeds 100 times /min, and can occur deterioration of hemodynamic state, may degenerate into ventricular flutter, ventricular fibrillation, resulting in sudden cardiac death, which requires active treatment.

  Causes of ventricular tachycardia

  1. Ventricular tachycardia caused by organic heart disease

  (1) coronary heart disease (CHD)

  (2) primary cardiomyopathy

  (3) mitral valve prolapse

  (4) myocarditis

  2. Ventricular tachycardia without organic heart disease

  (1) electrolyte disturbance and acid-base imbalance

  (2) drug and toxic effects

  (3) idiopathic ventricular tachycardia
