I recently had a frequent onset of PVCs (no history of heart problems), so for the last 4 weeks, literally nonstop >10,000 PVC's/day, which is obviously impacting my life and sleep pattern. All tests checked out OK (other than the abnormally small heart, the leaky mitral valve, the left to right PFO, Left Bundle Branch Block, fusion beats, and prolonged QT interval) in that there was no direct cause for the sudden onset of PVCs. The cardio recommended 1. do nothing, 2. fleccainide (with a 3 day hospital stay), 3. ablation. He said my PVCs would not respond to beta blockers but we can try it (that was not one of his options). I'm getting a second opinion on Monday.
Well, it has been 2 days on beta-blocker and my normally low bp and hr are now really low (as in 80/40 with a hr of low 40s), so numerous episodes of dizziness, etc. but with no change in PVCs. The cardio and I had a bit of a "falling out" last visit (apparently my appt. was interrupting him making his dinner plans and if I had any more questions, I'd have to schedule another appt. because he had another patient), so contacting him isn't an option. Thus my question: How quickly do PVCs respond to beta blockers, if they do (couple hours, couple days, couple weeks?)? Should I stick this out at least until Monday when I get my second opinion?
Thanks in advance for your help.
