Familial WPW syndrome: About three percent of WPW syndrome can have a familial occurrence and one of the genes identified is PRKAG2.

CPVT in short for catecholaminergic polymorphic ventricular tachycardia is probably the most lethal of the cardiac channelopathies.

Long QT syndromes have a phenotype of delayed depolarization due to ion channel mutations, causing QT prolongation and risk of ventricular arrhythmias.

Important cardiac channelopathies are the long QT syndromes, Brugada syndrome, CPVT, short QT syndrome and congenital sick sinus syndrome.

Syndromes in CHD (congenital heart disease)

Sudden death in young athletes could be due to hypertrophic cardiomyopathy, commotio cordis, coronary anomalies, aortic stenosis and long QT syndrome.

Hypoplastic left heart syndrome: hypoplasia of left heart at multiple levels - hypoplastic left ventricle, aortic atresia and a hypoplastic ascending aorta.

Innocent murmurs may be heard in up to fifty percent of normal children. Still’s murmur is a common innocent murmur of childhood.

Short QT syndrome is characterised by an abnormally short QT interval and a propensity to develop atrial and ventricular arrhythmias.

Intracoronary thrombus detection by CMR is by non contrast enhanced T1 weighted imaging, utilising the short T1 of methemoglobin in the acute thrombus.
