Inherited Arrhythmias and Sudden Death

Some arrhythmia conditions are inherited, and can affect entire families. At the Blalock-Taussig-Thomas Center, adult and pediatric electrophysiologists work together to care for families with inherited cardiac arrhythmia syndromes such as:

Specialists at our dedicated Familial Arrhythmia Clinic can see adult and child members of the same family on one day and at one location, making it easier for you if you live far away. The Familial Arrhythmia team includes specialized cardiac genetic counselors who can help you through the diagnosis of cardiac genetic conditions, and help you understand what they mean for you and your loved ones.

If you are pregnant and have had inborn heart problems affecting anyone in your family, we can coordinate genetic testing through Johns Hopkins’ Prenatal Diagnosis and Treatment Center to help you and your doctor understand any risk to your unborn baby.
