Hello Lois - Good to hear from you and so glad you remain pleased with your procedure decision.
When PACs occur, it's typically because you are low in potassium (and magnesium)... or as you mentioned, a food sensitivity ... especially if it can be associated with a meal. If you are gluten intolerant, then you absolutely have to avoid it continually. No choice.
More likely, it's that if you may be running low in the daily intake of core nutrients (electrolytes) magnesium and potassium that help maintain the consistent flow of "power" or electricity (voltage) or electrical conduction your heart requires. If so, then skipped beats are the result. Think of a flashlight beam that flickers when the battery is almost used up. Once you restore the power or energy source with a new battery, the light is strong and constant. In this case, low potassium allows the shortening of the refractory period or the time between beats, faster pulse or can proceed to outright arrhythmia or just be the attention-getting PAC activity. In other words, you have low voltage or low rate of electrical conduction.
It's important to assess not only your intake of the magnesium and potassium, but also intake of competing minerals that block the function such as ...calcium blocking magnesium and sodium blocking potassium's function. By any chance do you take supplemental calcium?
Refer to CR 72 and the importance of making sure that your sodium (salt) intake meets at the very minimum the 4:1 ratio - Potassium to Sodium. Packaged, processed and restaurant foods are typically loaded with salt. Unless you make a special effort to get your potassium up 4 - 5 or more times higher than the sodium, you will have PACs. Fresh whole foods do not have that sodium risk factor.
When I had some outright AF breakthroughs in the years 5, 6 and 7 post ablation, I reversed that trend by making sure that I was optimizing magnesium supplements and foods that were high in potassium count. Because I don't eat a carload of food, I also used and still do, potassium supplements.
I wrote a report that I called
The Strategy - What Metabolic Cardiology Means to Afibbers... based on my successes in turning around the Afib breakthrough events. That report is now in the process of being revised to include other key points that I neglected to mention initially ...mostly because they were such a part of my daily routine that I forgot to include. In part.. these are attention to maintaining an alkaline pH most easily achieved by using the magnesium bicarbonate water or WW (Waller Water), as well as eating an alkaline ash forming diet, nightly high-count probiotic to maintain good GI health and function, consistent use of the fibrinolytic enzyme Nattokinase, daily Iodine dosing and avoiding sources of fluoride... drinking water, beverages, fluorinated prescription medications and more.
Here are the links for your reading pleasure.
Let me know if I can elaborate.
Best to you,
Jackie
