I can understand the OCD and anxiety aspects. If you've been examined and determined to have benign rhythm issues, it's really more dangerous to treat them than it is just to live with them.
Beta Blockers are considered safe in treating them, though, and do so by slowing your heart rate (which can eliminate them for some people) and reducing the contractile force of the heart beating (which makes the ones you still get less noticeable). Ask your doctor to see if Beta Blockers would be appropriate for you. Oh, Beta Blockers block the effect of adrenaline on the heart (and depending on the Beta Blocker, may block adrenaline effects in other parts of your body).
Calcium Channel Blockers are also considered safe for treating certain benign rhythm issues.
I get premature ventricular contractions, I had 6000/24 hr on my first Holter this year, and 3900/24 hr on my second. How many do you get per day. In terms of the strength of the heart, for benign rhythm issues, the use 20,000/24 hr as the point, where if these went on day after day, that medication or ablation would be necessary, and at 20,000 that's 14/minute/24 hours a day.
Irregularities in heart rhythm, in otherwise healthy hearts, is quite common, and incredibly, most people that have them don't feel them.
