Hello,
It is worth having your rhythm evaluated with a
holterHolter monitor (24h) monitor. That should help determine how frequent it is. If it is frequent enough to capture on a 12
leadLead poisoning EKGAtrioventricular block, ekg tracing
Ecg
Exercise stress test, that is usually enough information to localize it in your heart within a few centimeters. This can be helpful if:
1. your PVCs are very symptomatic
2. They cannot be suppressed with medications
3. The decision is made to try an ablation
It is also important to make sure your heart function is stable. Hopefully you have a good adult congenital heart disease specialist. It may be worth seeing an electrophysiologist as well, especially if the bigeminy is constant.
Thanks for posting.
