A related syndrome, postural orthostatic tachycardia syndrome (POTS), is diagnosed when at least a 30 bpm increase in heart rate occurs with little ...
The prevalence of this condition has been studied in various populations. In a study conducted in 1922, it was found that 4.2% of 2000 apparently healthy aviators aged 18 to 42 years had an increase in diastolic blood pressure from below 90 mmHg while in the supine position to above 90 mmHg in the upright posture.
