Answer

In the United States, the most common setting for VT is ischemic heart disease, in which myocardial scar tissue is the substrate for electrical reentry. VT can also be seen in other conditions that create a myocardial scar, such as the following (see Etiology):

  • Dilated cardiomyopathy
  • Hypertrophic cardiomyopathy
  • Arrhythmogenic right ventricular dysplasia (ARVD) or cardiomyopathy
  • Chagas disease [10]
  • Surgical incisions in the ventricle
