What can cause a rapid heart beat?

Dr. Walter Pierce

Many things: Dehydration causes low blood pressure. The heart beats faster to compensate. Normal exertion should increase heart rate. Thyroid disease may cause it. And there are many abnormalities of the hearts electrical system that may cause a rapid heart rate.
