Dr. Bennett Werner
Internal Medicine - Cardiology
In brief: Low blood pressure
If the rhythm is fast enough, the heart doesn't have time to fill adequately during each cardiac cycle causing the BP to fall with dizziness and, if prolonged or severe, passing out.
For this to happen, the hr is generally >170 although it depends on your age and general condition.
