Postural orthostatic tachycardia syndrome

​POTS is not associated with increased mortality compared with the general population.[2]Sheldon RS, Grubb BP 2nd, Olshansky B, et al. 2015 Heart Rhythm Society expert consensus statement on the diagnosis and treatment of postural tachycardia syndrome, inappropriate sinus tachycardia, and vasovagal syncope. Heart Rhythm. 2015 Jun;12(6):e41-63. https://www.doi.org/10.1016/j.hrthm.2015.03.029 http://www.ncbi.nlm.nih.gov/pubmed/25980576?tool=bestpractice.com ​

Around two-thirds of patients on pharmacologic treatment will experience an overall improvement in their symptoms, and orthostatic symptoms tend to improve as the patient gets older.[8]Arnold AC, Ng J, Raj SR. Postural tachycardia syndrome - diagnosis, physiology, and prognosis. Auton Neurosci. 2018 Dec;215:3-11. https://www.doi.org/10.1016/j.autneu.2018.02.005 http://www.ncbi.nlm.nih.gov/pubmed/29523389?tool=bestpractice.com ​

The intensity of POTS symptoms commonly fluctuates. A flare in symptoms can be triggered by infections such as upper respiratory and urinary tract infections.
