how to improve heart pumping rate
I agree with itdood. Try not to worry about your upcoming procedure. RVOT ablation is very common. I wish you the best of luck with your surgery. I can relate to your situation, I have been dealing with PVC's since I was 15 years old. I'm now 24 and going for my 3rd ablation later this year.
Curious- were you on Rythmol all along, or did your doc try other medications first? I started out on acebutolol, then flecainide, then the propafenone (rythmol). The only drug that worked to control my arrhythmia was the flecainide, but the side effects were too harsh for me to stay on it.
You're probably referencing one of my posts. You're reading the post info wrong. I was trying to explain why medicating away ectopics is probably impossible.
The "backup" mechanisms are called escape beats, these can come from all sorts of sources in the heart. RVOT is a common source for ectopics, and a common site to have ablated. RVOT ablation has the highest success rate in reducing PVC load (if the PVCs are coming from that region). No one has ever died from having this done.
My EP said to me that the heart doesn't pump blood as the result of a PVC. It is a premature beat as the ventricle contracts before that ventricle has filled with blood; so it pumps nothing. I can't answer the other questions. Good luck to you with the upcoming ablation.
