Sudden Cardiac Death in Structurally Normal Heart

Posted by e-Medical PPT Tuesday, August 24, 2010
Sudden cardiac death is Unexpected death from cardiac cause within a short time (within one hour of the onset of acute symptoms) in a person without prior conditions that would appear fatal.Ventricular Tachycardia/Ventricular Fibrillation account for 80%.Primary Electrophysiologic Abnormalities that would lead to SCD are Wolf Parkinson White Syndrome,Brugada Syndrome,Catecholamine Polymorphic VT,Long QT Syndrome,Short-coupled TdP,Short QT syndrome and Idiopathic VF.
Short QT syndrome is a genetic disease inherited in an autosomal dominant pattern consisting of a short QT interval interval on EKG (≤ 300 ms) that doesn't significantly change with heart rate, tall and peaked T waves, and a structurally normal heart.Individuals with short QT syndrome frequently complain of palpitations and may have syncope (loss of consciousness) that is unexplained. Mutations in the KCNH2, KCNJ2, and KCNQ1 genes cause short QT syndrome.Currently, the only effective treatment option for individuals with short QT syndrome is implantation of an implantable cardioverter-defibrillator (ICD).A recent study has suggested that the use of certain antiarrhythmic agents, particularly quinidine, may be of benefit in individuals with short QT syndrome.
