Abstract
Abstract Several mechanisms underlying sudden deaths due to emotional trauma have been propounded. Emotional trauma has been known to be associated with hyperactivation of some physiyological systems including sympathetic system that may directly trigger malign arrhythmic events in arrhythmia-prone subjects or lead to some clinically serious conditions including acute coronary syndromes, Tako-tsubo cardiomyopathy (TTC) etc. that may have the potential to trigger sudden cardiac death (SCD). Besides these well known effects, emotional trauma may be associated with SCDs due to some genetically determined arrhythmogenic conditions including ion channelopathies (overt or obscure), particularly in relatively young victims with no apparent etiology of SCD suggesting thorough evaluation and genetic screening of family members of these victims for prevention of SCD.
