Ventricular tachycardia is a rhythm characterized by wide, bizarre QRS complexes and frequent ventricular premature contractions in a row. VT may be paroxysmal or chronic and often signifies underlying myocardial disease. Mechanisms include reentry, increased automaticity, and triggered activity. VT is potentially life-threatening, as it can degenerate rapidly to ventricular fibrillation and result in sudden death.
