I am 30 yr female. I have a baby girl that is 14 months old. I breast fed until her first birthday in october, but took awhile to dry up. Since i was about 23 or 24 i have had pvcs or pacs. Had several ekgs back then and thats all it showed. A few weeks ago while sitting playing a game on my tablet i felt my heart beating funny. No other symptoms. I took my pulse and it was fast then slow over and over again. Not really fast and not really slow though. Id say it would go from 70s to 90s back and forth. rhythmically. my husband is a nurse and he listened and heard it. It would be like five slower beats, then six fast, five slower, six fast. Over and over again. Woke up next day it was gone. Happened again a couple weeks later same thing so i went to my GP who said he thinks itz benign. But.ordered an echocardiogram (have a murmur) and 24 holter monitor. I got the results yesterday...echo completely normal. Holter monitor also good except occasional PACs, no PVCs. But of course i felt good thr day the monitor was on. Now basically every day since its been off my heart feels like its beating weird...lots of akips esp when i bend over or lay on my side or after eating. I think it has also done that speed up slow down again...but still knock on wood no other symptoms. I have really bad anxiety and cant be sure.if i am just overly sensitive to what i am feeling. I am constantly checking my pulse. I am not even enjoying the holidays with my daughter cause i keep thinking i am gonna drop dead and she will grow up without me. I google things and i know its stupid but i do. Now i am scared i am having runs of nsvt...but as i said the rate doesnt really get that high it just speeds up slows down but usually all within normal limits. Can NSVT runs happen like that...over and over again every few beats? Im going to see my dr next week to follow up and get a longer monitor hopefully. But just looking for some peace of mind until then.
