JR2000 Posted October 14, 2004 Report Share Posted October 14, 2004 Hi All:I am new here, and really appreciate the opportunity to tap into your experiences and knowledge. My main question is how to tell the difference between inappropriate sinus tachycardia and POTS. I seem to have overlapping symptoms that could include both. I recently had a stress echo. which was declared "normal". My heart rate shot up very quickly (over 150 in less than a minute on the treadmill), and I was out of breath and a little lightheaded. Echocardiogram looked mostly normal (very slight leakage of mitral valve - declared to be insignificant). I am wearing an event monitor. I have always had a rapid resting heart rate and it doesn't take very much activity for it to increase heart rate substantially (going up one flight of stairs as an example). My heart rate increases when crouching to standing (in the doctor's office it went from 85 to 140 when going from crouching to standing -- though this was ignored as well). I have fatigue and exercise intolerance. I have always had pretty low blood pressure (around 90/60). Any input anyone may be able to offer would really be appreciated. I'm not sure where to go from here. I'm supposed to see the cardiologist again in January, but he doesn't seem to really think there is anything serious going on.
