Overview

CT scan

Cardiac CT scan may be helpful in the diagnosis of the causes of cardiac arrest by evaluation of the following:

• LV volumes
• Ejection fraction
• Cardiac mass
• Anomalous origin of coronary arteries
• Coronary arteries calcification
• Pulmonary embolism
• Aorta dissection

2017AHA/ACC/HRS Guideline for management of sudden cardiac arrest and ventricular arrhythmia

Class I (Level of Evidence: C)

Coronary angiography or coronary CT angiography is recommended in patients recovered from unexplained cardiac arrest suspected ischemic heart disease
