Genetic Testing for
Inherited Heart Conditions
in London
Understand Your Heart Health — For You and Your Family
Some heart conditions run in families. Genetic testing for inherited heart conditions helps identify whether you or your relatives are at risk of developing a genetic cardiac disorder. At London Heart Group, we offer advanced, consultant-led cardiac genetic testing in London as part of a comprehensive approach to diagnosing and managing hereditary heart disease.
If you or a family member has experienced unexplained heart symptoms, sudden cardiac death in the family, or has been diagnosed with a cardiac condition at a young age, genetic testing may offer critical insight and peace of mind.
What Is Cardiac Genetic Testing?
Cardiac genetic testing is a blood or saliva test that looks for changes (mutations) in your DNA that are known to cause inherited heart conditions. These conditions can affect the heart muscle, electrical system, or blood vessels and may lead to arrhythmias, heart failure, or even sudden cardiac arrest.
Identifying a genetic cause helps understand the likelihood of being affected, helps to guide not only your treatment, but also the care and screening of close family members.
Who Might Need Genetic Testing for Heart Conditions?
Your cardiologist may recommend genetic testing if you or a family member has:
A diagnosed inherited heart condition, such as:
Hypertrophic cardiomyopathy (HCM)
Dilated cardiomyopathy (DCM)
Arrhythmogenic right ventricular cardiomyopathy (ARVC)
Long QT syndrome (LQTS) or other inherited arrhythmias
Brugada syndrome
Catecholaminergic polymorphic ventricular tachycardia (CPVT)
Familial hypercholesterolaemia (FH)
A family history of sudden unexplained cardiac death, especially under age 50
A history of unexplained fainting, seizures, or abnormal ECG findings
Children or siblings of someone with a known cardiac gene mutation
In many cases, genetic testing is part of a family screening programme to identify others at risk and allow early intervention.
