Sudden cardiac death (SCD) is generally defined as an unexpected death due to cardiovascular causes. In the majority of cardiac arrest patients, a structural or functional abnormality can be identified. Coronary artery disease is the most common cause of SCD . In younger individuals, SCD often occurs during exercise, where hypertrophic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy accounts for most of these cases . Myocarditis comprises 5–11% of SCD in individuals less than 40 years of age . In these cases, symptoms before the fatal event are rare . Secondary prevention of SCD needs ICD therapy after documented cardiac arrest unless a transient or correctable cause of the arrhythmic trigger can be identified . The treatment strategy for patients with ventricular fibrillation associated with a “transient” or “correctable” cause is not clear. These patients have a similar mortality rate as the survivors of ventricular fibrillation arrest in the...
