if u have those, sorry to say that but thats not normal and go see a doctor and let help yourself. I had in the passed heartproblems and believe me a hearttransplant is the last thing you want in your life.
TO ALL : Keep your heart healthy when u have the chance pls!!!!
I have had PVCs since high school. Then i was getting up to 5 a min, the doc was not worried. Low potassium level can make them worse and ANYTHING that stimulates ( smoking, caffeine etc) can make them worse. Caffeine is a double wamny since it stimulates AND can wash potassium from the body (caffeine is a diuritic). I don't smoke ( never have) but I am a caffeine addict.
PVCs are harmless, aside from being a little uncomfortable. If they become extremely frequent (like every other day) then go to your primary care provider and they can assess the problem from there. Most people will have multiple episodes of PVCs in their lifetime. I wouldn't worry about it. Next time it happens you can try laying flat and then bearing down for a count of ten and that should help the problem.
