New Delhi: One of the long-term side-effects of Covid-19 found in many people include Postural tachycardia syndrome or PoTS, an abnormal increase in heart rate that occurs after you sit up or stand. Also known as postural orthostatic tachycardia syndrome, this ailment affects a range of people but is most common among women aged 15-50 years of age.
According to health experts, many post-Covid19 patients mistake their rapid heartbeat to be anxiety, when it could be PoTS. Doctors say PoTS often improves gradually over time and some medicines help, but the condition does affect the quality of life of a person suffering from it.
Doctors say as soon as you sit upright or stand, gravity pulls some of the blood down to your stomach, hands, and feet area. However, as response to that the blood vessels quickly narrow and the heart rate goes up rapidly to maintain blood flow to the heart and brain and prevents the blood pressure from dropping.
In PoTS, the autonomic nervous system does not work properly. There’s a drop in blood supply to the heart and brain when you become upright and the heart races to compensate for this.
