I don't know which comes first. Upset Stomach then PVCs or PVCs then an upset stomach. I did notice before I got overly anxious about my heart skips, several years ago, I thought I needed to go pass a BM to help them, which sometimes it did.
My PVCs and flutters have really calmed down these past few days. Of course I completely halted everything bad in my life. I look at it as a test to see what is causing the imbalance which leads to my heart skips.
High Protein Diet, No Soda/Caffeine, No MSG/Processed Foods, Quit Nicotine, Reduced Alcohol to 0-1-2 drinks a day (usually save up till the weekends and have 5 or 6, but likely to have skips next day), no sugar free products at all! Hope this helps. Zach
