Is there a possibility of having POTS without the "tachycardia" associated? My medical history; Systemic Sclerosis with some Lupus overlap X 15 years. This includes GI, Pulmonary, severe Raynauds issues. Currently being worked up since being diagnosed with Disautonomia/POTS 6 weeks ago, via CPET (advanced cardiopulmonary exercise test), and also Spherocytosis. Waiting for hematology workup at Dana Farber in Boston, and skin biopsy at Mass General. The one symptom I don't experience is rapid heart rate. I DO absolutely have massive heart palpitations / pounding 24/7, even when supine. My heart rate hovers around 70bpm and my bp has always run very low. Thank you in advance...
