I have had skipped beats for 4 years now. I have had a nuclear stress test, 3 EKGS, 2 ultra sounds and 2 24hr holter moniters done, the last was a 24 holter done about 1 1/2 years ago...how long do these tests stay "ok" for? I was so stressed out on Saturday which is why I am guessing they started yesterday, but the beat beat beat.....THUMP feels a little different...can anyone advise on this? Or gone thru it? I was scared to go to bed last night and scared to move today. Any advise or words of encouragement would be so appreciated!
