I had, on average, 20-30,000 ectopic beats every day,
and 6-700 runs of SVT per day. Most of my episodes occur at night. From 10pm to 6am, my hourly burden of PACs/SVTwas 30-80%. It starts in the evening and then keeps me awake constantly. The meds have all been a disaster. I have had two ablation attempts with failure to induce. The last ablation attempt caused pericarditis. I was.taking Metoprolol, which I have taken before and it always seems to stop working.
