Hypnosis for pvcs

I have no such experience, so please take what I offer back to you with an open mind: while hypnosis, or anxiety-reducing medications like Ativan might work as a palliative, or as a planned temporary measure for relief from symptoms or the associated anxiety, simply masking a potentially problematic arrythmia and/or its symptoms is not likely to be useful long term. It might make you feel complacent, forgetful, and so calm and indifferent (if grateful) that your condition begins to worsen unbeknownst to you...and your caregivers.

I guess I would counter with, what are your aims? Will this be repeated a number of times, or meant to last until the hypnotist 'releases' you? Do you merely wish to avoid medications? If you have atrial fibrillation, even for a few fleeting seconds (and it does often accompany diagnosed PACs) you would want at the very least to be on a DOAC (direct oral anti-coagulant) such as Xarelto or Eliquis.

I sometimes do Reiki or even take 1/4 Klonopin when I feel a certain pressure that makes me think afib might be coming. I also do tai chi. I do think that something like hypnosis might calm your system to head off trouble, but I wouldn't recommend it to "hide" symptoms (as @gloaming said). Stress is a trigger for arrythmias and hypnosis might reduce it, for a few days at least (or hours?). A doctor actually suggested it to me yesterday for some autonomic neuro issues.

I have had 10 afib episodes in 10 years. I land in the hospital every time due to low bp making treatment difficult. These episodes last 45 minutes to 7 hours. I am still not on anti-coagulant or daily meds. I probably will be in the future though. It depends on your CHADS score (ask your doctor or look it up online): high bp, diabetes, weight, age, gender etc.

So Reiki, tai chi, hypnosis, EMDR, exercise, good company, art, therapy, anxiety meds can all have a place in reducing stress which may be a trigger for your PVC's and PAC's. But hiding palpitations is probably not possible. Whether it's a good idea or not, is something to discuss with your doctor!
