Sarah your pretty much right on. It is a abnormal fast heart beat caused by a arrhythmia problem that originates above the ventricles.

Here is some information from the Heart Center On Line. It is their definition of SVT.

Tachycardia” is a general term for a variety of different conditions that cause the heart to beat more than 100 times per minute. There are two general forms of tachycardia that may be diagnosed.

The first type is supraventricular tachycardia — a condition in which electrical impulses traveling through the heart are abnormal because of a cardiac problem somewhere above the lower chambers of the heart (ventricles). Common examples of supraventricular tachycardia include atrial fibrillation, atrial flutter, AV node reentry and Wolff-Parkinson-White syndrome (WPW).

The second type is ventricular tachycardia — a condition in which the cardiac abnormality is somewhere in the ventricles. Examples of ventricular tachycardia include premature ventricular contractions (PVCs) and ventricular fibrillation.
