I have been told I have PAC's and PVC's. I have also been told I have a completely normal heart. I get these feelings like a small jump or catch. On occasion, about eight times in the last month, I get these sensations like I have been hit in the chest. Like my wind gets knocked out on me, briefly, and maybe one or two times consecutively. Almost like a little seizure type feeling in my chest, that sends my into an instant panic, my heart races afterword and pounds seemingly twice as hard and I get more skips. And on one occasion, after the weird sensation for a few seconds in felt like my heart was gone, chest void and I couldn't pick up a pulse in my wrist for a few seconds. I know there's other post on things like this, but I'm still a little lost. Are these PVC's, something worse? ANY info would be greatly appreciated! I'm so scared of doing anything these days, I get scared that the next time it happens my hearts going to stop for good! Is is bad to have these things a couple of times a day or am I making a big deal out of nothing. The cardiologist I saw said I was totally normal but I sure don't feel normal.
