No, no experience from me. However, if you're open to my thinking, I'll offer this:

A defibrillator must be monitored periodically and must be maintained/replaced when needed. An ablation, if the first one works, is a one 'n done. If your arrhythmia is fixed, you also won't need any medications...ostensibly. You'll still need them if you have a defibrillator...or I THINK you may have to.

I'm not a doctor, so I don't know if you should be on an anti-coagulant for your condition. But, you might also need that in addition to the metoprolol if you need a defib to correct an arrhythmia now and then. If so, yet more drugs, maybe not now, but later if your heart continues to remodel itself, or if you develop SVT or...whatever.

Can they not repair the disjunction?
