After 18 months of having unstable high blood pressure with palpitations, with quite bad flushing of upper body and face plus nausea and sudden diahorea, i was diagnosed with Hypertension, Autonomic dysfunction inappropriate sinus tachycardia and postural orthostatic tachycardia syndrome, i would like to know what this means in real terms.
Autonomic dysfunction inappropriate sinus tachycardia or postural orthostatic tachycardia syndrome is simply a high heart rate over 100 due to swift change in position like when you stand up too fast. This causes your BP to drop so your heart rate increases to normalize your BP, it is very common. You have blood pool in parts of your body that is needed elsewhere to regulate your BP with higher demand such as standing up so for the brief period of time when that pooled blood is moved, you get faint and may pass out and the only way your body knows to correct the problem is to speed up your heart. It's unpleasant but not dangerous that I know of, just be careful if you feel you are going to faint.
