Meditation vs. Medication

Meditation 'might' help, but in my inexpert opinion you are experiencing natural aging effects, of which introduction to AF is common for about 5% of all aged American and Canadian adults.
My thinking is that your WPW was successfully treated as a unique situation/condition in your youth, but like so many aging people, we suddenly find that our hearts have begun to create and to deposit rogue signalling cells in our atrial substrate. We start with paroxysmal AF (comes and goes on its own), and the 90% probability is that the rogue cells are found in the pulmonary vein ostia on the rear wall of the atrium. A PVI (pulmonary vein isolation) is most likely what is ahead for you (again, I'm just guessing here, I know nothing else about you, your history, other comorbidities, the condition of your heart valves, etc)
We all find that we have triggers for AF. For some it's worry, anxiety, lack of sleep, poor diet, insufficient magnesium or potassium in our diet (or too much of it), other drugs, other stressors such as pathology and comorbidities, eating too much each meal (so stomach distension), acid reflux, coughing, sneezing...I could type here until supper time about what people swear is the No. 1 bringer-on of AF.

Thanks for your response. I find that either the PACs are less or I just don't notice them when I'm walking the golf course. I'll have to do some monitoring to see what helps/hurts.

The bodymind connection and meditation. Everyone says they can't turn off thinking. If we think (brain) into our past, we can trigger an emotion (body reaction hormones/neurotransmitters) . Same with projecting thoughts into the future. Our body reaction includes signals to the heart as in "When I saw her, my heart skipped a beat," or "My heart stopped when I got the news."
So, aside from attaining Nirvana or Enlightenment, if you can turn off thinking with meditation (natural) instead of ingesting something unnatural, the silence/vacuum will give the body a break. Meditation may not cure, but it can help, and it's free.
Also, if you adopt a regular neditation posture 🧎‍♂️🙏, the body will signal the brain that it's time to turn off the chatter for awile, hence the Body/Mind circuit.

Thanks for your response. I agree - the mind has a very powerful effect on what's going on in your body, be it good or bad. I had a very positive experience with a health problem 10 years ago after attending an 8 1/2-day meditation retreat. It's definitely worth giving it a try.

Stress is certainly one of my triggers.
For the past year, every Afib episode has been preceded by stressful events.
These events can be physical, mental, or emotional, often in combination.
Handling these stressors is key for me.
It wouldn't hurt to try mind-body techniques and see if they're helpful.

Thanks for your reply. I have had success with meditation in a previous health problem so I think that will be my first line of defense.
