Genetic sudden cardiac death syndromes

• Genetic Determinants of Sudden Cardiac Death | Circulation

  The symptoms of genetic arrhythmias (like LQTS) are frequently misdiagnosed as vasovagal syncope, asthma or epilepsy without any cardiac evaluation. Thus, the opportunity to diagnose and treat LQTS and related disorders is missed. Most cardiac arrhythmias and structural defects that may cause sudden death in the young are treatable.

  The Jervell-Lange-Nielsen syndrome – the combination of a long QT interval and congenital deafness was the first of the Long QT syndromes to be described in 195721. Finally a comprehensive family history should be taken. A family history of LQTS or unexplained sudden cardiac death raises the likelihood of the index case having LQTS.

  Long QT syndrome may be caused by mutations in cardiac sodium channels. Acquired and inherited long QT syndromes may both cause ventricular arrhythmias arid may have a similar molecular basis. 35. Familial hypertrophic cardiomyopathy (HOCM) is a disorder largely affecting cardiac myocytes.

  These syndromes cause cardiac arrhythmias in seemingly healthy and often young individuals and can lead to syncope, seizures, cardiac arrest, and sudden death. LQTS and Brugada Syndrome are two of the more common causes of sudden death in young people, resulting in 2,000 to 3,000 deaths per year.

  replacement of the right ventricular myocardium are pathognomonic hallmarks of ARVC, which predispose to ventricular tachyarrhythmia and sudden cardiac death (SCD). Clinical findings are limited to the heart in most individuals, although there are some genetic syndromes associated with ARVC and other clinical findings.
