Susan O'Donoghue, MD, discusses the burgeoning field of cardiogenetics, which can help identify various certain inherited cardiovascular disorders, particularly those that are based in the heart's electrical system. Potential candidates include individuals who have fainted due to physical exertion or who have a family history of unexpected cardiac arrest and/or death at young ages. Dr. O'Donoghue also explains the importance of genetic counseling pre- and post-screening and guidance on when a molecular autopsy might be in order.
