Depends. The level of testing required when a pilot has Wolff-Parkinson-White syndrome depends on the type of flying intended - military, airline transport, commercial, private, sport, recreational, etc. Having WPW does not exclude you from flying.
Wpw . Yes.
WPW. The danger with WPW is of a very rapid rhythm. If the patient has no history of this, then flying in a pressurized aircraft should present no excess risk. For a patient having arrhythmia s , the risk is more and they should probably not fly unless their problem is ablated and resolved.
Wpw. Usually yes, but for patients with difficult to control SVT attacks I would recommend consulting your doc especially for long flights, if one is having Svt attacks, the treatment is Catheter ablation ...
Yes. As long as the rhythm is stable, the person can fly.
