Arrhythmia: You may have an arrhythmia that can be easily diagnosed with an electrocardiogram and treated/ cured by a procedure that is done regularly called cardiac ablation. Please look into seeing a cardiac electrophysiologist... They are specifically trained in taking care of arrhythmias. If left untreated the fast rhythm may weaken your heart muscle.

Could be dehydrated: Recommend to drink lot of fluids and fluids with electrolytes. If does not get better, get checked out with ekg, orthostatic BP etc.
