StayAtHomeMom Posted June 4, 2017 Report Share Posted June 4, 2017 This has probably been covered before but I am curious. I have been diagnosed with POTS by failing my tilt table, but I always thought it was weird I have a high resting heart rate. I know since I was a teenager my resting heart rate has always been in the 90s. I assumed because I smoke it has always been high but now I am beginning to wonder. According to my garmin when I sleep I average about 64, but awake and laying in bed watching t.v. I average 95-100. Anyone else notice this? I looked into IST when my PCP mentioned as more probable but dismissed it because it doesn't cause dyspnea. But recently I noticed it can cause it. Standing makes my shortness of breath worse but I always have it, do you think I should bring it up with my doctor as an alternative theory? The odds of having both seem slim but it makes me wonder, since I don't seem to fit perfect within the POTS diagnosis considering I have symptoms laying down as well.

BuffRockChick Posted June 4, 2017 Report Share Posted June 4, 2017 I think IST is worth looking into. With IST, the 24-hour average heart rate is >94 bpm with a nocturnal dip. From what I gather, SVT has to be eliminated in order to diagnose IST. Have you looked at SVT symptoms, patterns, diagnostic criteria Quote Link to comment Share on other sites More sharing options...
StayAtHomeMom Posted June 4, 2017 Author Report Share Posted June 4, 2017 All I know is my 24-hr holter monitor showed no arrythmias, and my EKG and echo were normal. I was concerned because my dad has a-fib but my cardiologist said it looked fine. Wouldn't they have ruled out SVT or IST before he gave me my POTS diagnosis?
