Inherited Cardiac Conditions
Inherited heart conditions are caused by a fault (or mutation) in one of more of our genes. If a parent has a faulty gene, there’s a 50:50 chance you could inherit it. If you do, then there’s also a 50:50 chance you could pass it on to each of your children. Most inherited cardiac conditions follow this pattern; there are rare exceptions when a particular faulty gene can only be passed on by a mother.
The most common inherited heart conditions are:
- Hypertrophic cardiomyopathy
- Dilated cardiomyopathy
- Arrhythmogenic (right) ventricular cardiomyopathy
- Non-compaction cardiomyopathy
- Restrictive cardiomyopathy
Inherited heart rhythm disturbances:
- Long QT syndrome (LQTS)
- Brugada syndrome
- Catecholaminergic polymorphic ventricular tachycardia (CPVT)
- Progressive cardiac conduction defect (PCCD)
