Hi, some of my history with PVCs, a little advice, and some links.
I'm 55+, and have had intermittent rhythm issues since I was in my teens. They come and go, and as I age, they come more often and go less often. I get PVCs, PACs, have had PSVT, and infrequently couplets and short salvos.
1. Have you seen a doctor and discussed your concerns with him/her? If you've been cleared medically, realize that PVCs and PACs are a common occurrence in people. The hard to believe point is that while many people have them, most of the people that have them can't feel them. Rather than like many of us that do feel them, many people are only aware of feeling light headed, or short of breath (if they would have too many), and only then, after going to the doctor, do they find out. My wife worked for a cardiologist, they had a patient one day with PVCs so bad she couldn't take his pulse. After doing the examination, the doctor took the patient's pulse and asked if he ever gets "skipped beats". He replied "no". The doctor never even made him aware that he was getting them, he knew they were harmless in his case and didn't want to alarm him.
2. Anyone getting PVCs or similar for the first time should see a doctor. Same for those of us that get them frequently but notice them getting worse. They're usually harmless, but see a doctor to be sure.
3. My previous bout of rhythm issues started last Easter and lasted for many months, I suspect I over did the chocolate. The day after Easter I was having tons of them, went to the hospital, and for each 3 PVCs was getting 1 PAC. I was sent home with a diagnosis of frequent PVCs. Went to my cardiologist, wore a Holter for 24 hours, and I had 6000 PVCs in 24 hours. That's about
5 per minute 24 hours a day. Since I didn't get them at night, that averaged to more than 5 per minute while awake. Months later showed 3900 PVCs/24 hours. I was in very frequent bigeminy as well. Change in medicine, change in eating habits, and months later, they finally subsided. 20,000 per day, if no electrical, vascular, valve, or structural problems exist with the heart would be considered the maximum, and this would have to go on day after day for weeks before it would begin to contribute to weakening of the heart.
4. I have PVCs made worse or brought on by swallowing and intestinal activity, sometimes. The Vagus Nerve is connected to your heart and digestive system. For the heart, its purpose is to slow it down after being scared or angry. For the intestines, its purpose is to speed-up digestion. When you're scared, you're heart races and digestion slows, when you relax, your heart slows and digestion increases.
5. Avoid stimulants like coffee and chocolate (Caffeine and in the chocolate, caffeine and there are other things as well), smoking (Nicotine), diet or cold medication that speeds up your heart, illegal drugs, etc. Get PLENTY of sleep and try to avoid stress. Eat smaller meals, eat less fat and less sugar. Don't overeat.
