Black outs: Please see your doctor. Your blood pressure MAY be too low and when you stand up it takes a few seconds for the proper amount of blood to get to your head. Your doc will help. Peace and good health.

Syncope on standing: May be a delay in adjusting your blood pressure autonomically when going from lying to standing. When you stand blood pools in the lower extremities, therefore there is less for the brain, until the vascular system constricts. Make sure you are hydrated- dehydration worsen this, , stand up slowly. F/U w/ cardiologist regarding autonomic function, EKG for QT interval, arrhythmia, echo for ASH
