Without a doubt the most common cardiac complaint on this forum. Search the last couple of pages, and find a large number of posts regarding PVC's. It's always wise to see you physician, but most likely, these are benign, albeit annoying events.
Sounds like your experiencing PVC's or PAC's like me, or a quick Run of PVC's together. Go see your GP. He will send you for a blood test and 24 hour ECG. But, you should know these are normal and happen to everyone, some people feel it some don't, they can create a great deal of health anxiety which leads to more. Right now your probably thinking there might be something wrong with your heart. Don't worry
If your blood test and ECG are Normal and you are still worried, get an Echo-cardiogram, if that is also normal and your heart is Structurally normal then you have nothing to worry about, your palpation's will eventually stop on their own.
