PY - 2017 T2 - Hurst's The Heart, 14e AB - Sudden cardiac death (SCD) describes an unexpected natural death resulting from a cardiac cause within a short time period after the onset of symptoms in a person without a prior condition that would appear imminently fatal. It is most often caused by a sustained ventricular tachyarrhythmia (ventricular tachycardia [VT] and ventricular fibrillation [VF]). Although many cardiovascular disorders increase the risk of SCD, the presence of preexisting cardiovascular disease is not necessary, and SCD may be the first manifestation of overt cardiac disease.1,2 Prodromal symptoms, such as palpitations, chest pain, or dyspnea, may suggest a cardiovascular etiology such as arrhythmia, ischemia, or congestive heart failure, but are not specific.
