Overview

Coronary angiography is used in the diagnostic evaluation of ventricular tachycardia in survivors of sudden cardiac death and life threatening ventricular tachycardia. Coronary angiography is used to rule out the presence of coronary artery disease in these patients.

Coronary Angiography

required urgent revascularization.[1]

2017 AHA/ACC/HRS Guidelines for Management of Patients With Ventricular Arrhythmia

Class I
"1. Coronary angiography is recommended in survivors of sudden cardiac arrest suspected ischemic heart disease for guiding decision about appropriate coronary revascularization (Level of Evidence C)"

Electrophysiological study
