Hi, I've had issues with PVC's for a couple of years and I'm familiar with what they feel like. The past few weeks I've been feeling a chaotic fluttery beat right under my left breast. It usually lasts about 5 seconds and happens a few times a day. I had a normal echo and ecg, and the cardiologist said it's very unlikely in feeling VT, but it's probably just a benign palpitation felt in the"bottom tip" of my heart. What concerns me is that would be the ventricles so how is that benign? Wouldn't that be VT potentially? I did a 24 HR holter but of course it didn't happen while I was wearing it. She thinks it's happening because I'm dehydrated and sleep deprived because I just had a baby. Also I've been feeling dizzy and lightheaded and my blood pressure has been super low around 90/53. I'm so worried about it being dangerous or converting to V-fib
