Did you know that Postural Orthostatic Tachycardia Syndrome used to be called irritable heart syndrome? In the first part of this two episode series, Dr Mark Donohoe returns to FX Medicine to discuss Postural Orthostatic Tachycardia Syndrome, or POTS, a condition affecting the autonomic nervous system. POTS occurs when an inadequate amount of blood returns to the heart when the patient moves from lying down to a standing position.  Mark guides us through the definition and history of POTS, providing an in depth discussion of the symptoms that define the syndrome, the challenges for practitioners in alleviating those symptoms, and the connections between POTS and other conditions such as Chronic Fatigue Syndrome and Ehlers-Danlos syndrome.  Find today's podcast transcript and show notes here: https://www.fxmedicine.com.au/podcast/postural-orthostatic-tachycardia-syndrome-pots-part-1-dr-mark-donohoe*****DISCLAIMER: The information provided on FX Medicine is for educational and informational purposes only.
