I would strongly recommend getting a second opinion regarding your diagnosis and medications. You will see us on MCC always suggesting second opinions on things like this. It comes from personal experiences of dealing what you are dealing and then getting second opinions from experienced medical professionals.

The carvedilol you mentioned is a medication to help with heart arrhythmias, palapations, PVCs, tacacardia. This comes from my Mayo Heart Failure doctor and EP. When you came off carvididol your symptoms got worse is that correct?

Consider getting a second opinion. Do you live anywhere close to a Mayo Clinic, Cleveland Clinic, John Hopkins, etc. ?

Ask your cardiologist about magnesium. My EP recommended that to me for PVCs. I think it help some. But what really helped was my EP put me on an additional medication to help with PVCs, tacacardia, and it really helped. The only down fall is that is must be taken every 8 hours. It has a very low toxicity and leaves body fairly quickly thus the every 8 hours. I had asked for an ablation but since my electrical problem was coming from 3 different areas in LV wanted to try it.

We are all different and what one medicaion works for our case may not work for you. My HF, EP, emphasize that stress and anxiety will cause more PVCs, palabatations, etc. It is important to address your stress and anxiety as well. This can be consulations and of course medicaion if deemed necessary. I do a lot of exercise (doctor approved and hobbies).

It is important thus to have a cardiologist you trust, is experienced with not just cardilogy but electrical functions of heart. That is why you will see a lot of us on MCC suggest seeing a Electrophysiologist (EP). They are experts in the elecrtricl function of heart which affect, PVCs, PACs, palapatations, heart arrymthmias, etc.
