pots syndrome symptoms webmd
The condition is so named because those who suffer from it have a heart that's too small. The medical term for the condition is POTS, short for postural orthostatic tachycardia syndrome. About 500,000 in the U.S., mostly young women, are affected. Among other symptoms, those with POTS have a rapid increase in their heartbeat when they change from lying down to standing. The volume of blood pumped out from the heart with each beat is low. That can make it difficult to stand for long periods. Quality of life can suffer greatly.
