Abstract

The true incidence of cardiac arrest in apparently normal heart is difficult to estimate. Historically 10 - 15% of all cardiac arrest are in apparently normal heart whereas, up to 40% cardiac arrest in young are in apparently normal hearts. Majority of the cardiac arrest in normal heart is due to recurrent ventricular arrhythmia caused by abnormalities in myocardial depolarization and repolarisation, usually due to inherited channelopathy, metabolic or drug induced. Any survivor of sudden cardiac arrest require a comprehensive clinical and in depth sequential testing such as resting and exercise ECG, echocardiography, angiography and various provocative test and genetic testing if needed. General and cardiological evaluation of family member of victim of sudden unexplained cardiac arrest may yield the presence of heritable condition in up to 40% of family members. All first and second degree relatives of sudden cardiac arrest victim in the absence of any overt heart disease should be informed regarding the potentially increased risk of cardiac events and counselled for assessment at a center with experience in the diagnosis and management of inherited cardiac conditions and genetic testing should be undertaken whenever any identifiable condition exist. This review focus on the common conditions leading to cardiac arrest in an individual with apparent normal heart and approach to evaluation and diagnosis of the victim and their close family members.
