I had a echo stress test in late August and during the first few seconds of the resting echo part My heart rate went from 61 to 160. I have been experincing this for a while and it makes me feel like I am going to pass out and I get very hot. This past Mon. night My heart started acting funny again and continued for a hour so my husband took me to the ER. It lasted 5 hours. They said it was PVT. I am having them still , not that long of course but having them just the same. I was put through a heart cath & cat scan and x-ray. I have to wait another week to get a holter moniter, I am also light headed and tired all the time. Should I be worried? I am very scared and dont like this feeling and the heavyness and pains in my chest
