Covid is causing a sharp rise in cases of postural orthostatic tachycardia syndrome, a disorder of the autonomic nervous system that causes rapid heart rate, fainting and dizziness
POTS stands for postural orthostatic tachycardia syndrome, a disorder of the autonomic nervous system, which regulates involuntary functions like heart rate, blood pressure and digestion.
“When the autonomic nervous system is not functioning properly, any or all of those things can go a little haywire,” said David R. Fries, a cardiologist and POTS specialist at Rochester Regional Health.
POTS patients typically experience a marked rise in heart rate when standing and a complex combination of symptoms, including dizziness, brain fog, fainting, headache and fatigue, among many others.
There is no known cure for POTS, but physical therapy, medications and diet changes related to salt intake can sometimes help.
Experts say there is a dire shortage of medical professionals who know how to care for patients with POTS. Lauren Stiles, president and chief executive of Dysautonomia International, a nonprofit advocacy group, estimates that the number of people with POTS has at least doubled since the start of the pandemic, while the number of specialists has remained the same and waiting lists are getting longer.
“They were overwhelmed and flooded long before covid,” Stiles said “We need to increase the amount of experts in this because it wasn’t enough before covid, and it’s certainly not enough now.”
POTS symptoms are often diagnosed as anxiety
Symptoms can vary widely, and in some cases, can be debilitating.
Angelica Baez, 25, of Sacramento, got sick with covid in March 2020. Soon after, she developed unusual symptoms, including tingling hands, frequent diarrhea and either feeling extremely cold or extremely hot. But the most debilitating symptom was that she almost constantly felt dizzy. She often felt like she might pass out and had trouble walking long distances.
“My heart started going insane. I could feel it pounding in my chest,” she recalled. “I literally felt like I was going to die.”
Just standing up or walking across the kitchen caused her heart rate to spike to 160 beats per minute, and she frequently rushed to the E.R., worried that she was having a heart attack. She tried consulting various doctors but was dismissed because nothing seemed wrong with her heart or overall health.
