Heart & Cardiology/Electrical rhythm issues


Hi Dr Richardson,

I've had normal echos (two done) and a normal cardiac MRI...My questions are:

1. Those electrical disorders that are more dangerous (Brugada Syndrome, LQTS, PVST) are they genetic or do they manifest anytime in life?....Can one still get these rhythm disorders in a normally structual heart?...


Hello Rick,

Brugada and LQTS are hereditary but can be manifest later in life.  Paroxysmal supraventricular tachycardia is also congenital, that is one is born with a bypass tract, but SVT may not occur until later.

Please write back if this doesnít answer all your questions.
