text: Coronary angiography has an important role in diagnosis and  treatment of myocardial ischemia-induced life-threatening VT, VF. Myocardial ischemia may induce recurrent  polymorphic VT, or VF and is treatable by coronary revascularization.
  Evidence of ST segment elevation or early post resuscitated ECG changes suggestive of ischemia may lead to ventricular arrhythmia and sudden cardiac arrest and required urgent revascularization. In patients with low evidence of myocardial ischemia, coronary angiography is not recommended. For patients suspected anomalous origin of the coronary arteries leading SCA , coronary angiography is warranted.
