Is wpw syndrome a genetic disease?

Yes: While WPW syndrome is genetic, not every patient behaves or is treated the same way. A good percentage of the WPW population will not need any treatment as they do not have fast heart rates (arrhythmias). At the other end of the spectrum however, live patients with WPW who may need ablation or possibly an icd. The proper course of action is determined by an electrophysiologist usually.

No : In the majority of cases, it is not inherited although it is more common in conjuction with certain congenital anomalies, some of which may or may not run in families.
