It changes greatly for me. at one extreme it's like a mule kicked me in the chest. At the other extreme it's a little tickle followed by pressure in my chest and throat.
There are a lot of mechanical and electrical reasons why it varies so much. Too numerous for me to even start to document. It's related to the timing of the PVC, autonomic nervous system tone, circadian hormones, stress hormones, source of the PVC, and all these variables are intertwined to a level of complexity I can't wrap my head around. This is why PVCs have such a diverse personality.
I can give you an opinion based on my arrhythmia that MAY be what others experience as well. My PVCs come and go. I experience clusters of them that will last for several days, them may disappear for days, even weeks at a time. Most of them occur during the warmer months, and disappear completely during our cold winters. I experience two types of "skips". I get predominantly PVC's, but I also experience PAC's as well. My PVC's feel like a right in the center of my chest just below the sternum. They are quite noticeable, and there's no mistake when they occur. I also may experience an occasional PAC. These sometimes occur during heavy physical output, and was confirmed during a stress test. When I pointed out to my cardiologist who was administering the test that I was felt a light PVC, he informed me that I was throwing an occasional PAC. So now I knew that a PAC felt much lighter than a PVC. I can definitely feel it, even while running. But it feels much lighter. The cardiologist looked at the data, and really didn't feel that it was anything to be alarmed about and well within limits or "normal". There is never any accompanying symptoms. I sometimes will experience PVC's prior to becoming ill with an infection like a sinus or upper respiratory illness. I've heard others state this as well, although I don't know if there's a connection or not.
What I've learned from this forum during the last 5 years is that what I feel, may not be the same as what you're feel, and that neither one of us is right or wrong. If you trust your cardiologist's diagnosis, move on with his recommendation and don't second guess what's he's telling you.
