Orthostasis (or other mild physical stress) triggers a cascade of inappropriate tachycardia, lightheadedness, palpitations, and often fainting. Postural orthostatic tachycardia syndrome is characterized by orthostatic intolerance. Resolution of Postural Orthostatic Tachycardia Syndrome After CT-Guided, Percutaneous T2 Ethanol Ablation for HyperhidrosisĮnergy Technology Data Exchange (ETDEWEB)īrock, Malcolm, E-mail: [Johns Hopkins University, Department of Thoracic Surgery, Center for Sweat Disorders (United States) Chung, Tae Hwan, E-mail: [Johns Hopkins University, Physical Medicine and Rehabilitation (United States) Gaddam, Sathvika Reddy, E-mail: Kathait, Anjaneya Singh, E-mail: [Johns Hopkins University, Vascular & Interventional Radiology (United States) Ober, Cecily, E-mail: [Johns Hopkins University, Department of Thoracic Surgery (United States) Georgiades, Christos, E-mail: [Johns Hopkins University, Vascular & Interventional Radiology (United States) This analysis confirmed in our patient a strong activation in sympathetic tone. Power spectral analysis of heart rate variability (HRV during the tilt test revealed that the ratio of low and high frequency powers (LF/HF increased with the onset of orthostatic intolerance. Heart rate variability analysis in postural orthostatic tachycardia syndrome: a case reportĭirectory of Open Access Journals (Sweden)įull Text Available The authors present a case of 36 year old male patient with idiopathic postural orthostatic tachycardia syndrome (POTS diagnosed during head-up tilt testing.
