Probably 'begnin': The electrical system of the heart sends regular pulses to the heart muscle to signal it to contract. Many things can disturb this natural rhythm eg electrolyte abnormalities (low potassium or magnesium), excessive stimulants eg caffeine, alcohol, nasal decongestants, certain asociated conditions such as mvp (mitral valve prolapse), anxiety, hormonal fluctuations, dreams etc.

How can I tell if my heart is racing or just high hr?

Situational: If your hr is high due to exercise, fever, excitement or anxiety, it may be simply a high hr. If you are at rest and have a high hr, almost too fast to count, it is likely "racing" or abnormal. If you have concerns it is best to ask your doctor and appropriate testing can be done as indicated.

SVT: The most common cause is something called supraventricular tachycardia. I get this if i let myself get out of good aerobic shape. A physician's office visit is in order, for treatment and to rule out something more troublesome.
