The heart is a muscle that pumps blood throughout the body. It is stimulated to beat by an electrical system that sets the heart rate. This is typically 60-90 beats per minute at rest and faster with activity.

Electrophysiologists, or EP's, are cardiologists who specialize in heart rhythm disorders. They are referred to as "electricians' as opposed to the "plumbers" that deal with blockages in the heart arteries.

Electrical problems can result in heart rates that are too slow (bradycardia) or too fast (tachycardia). Tachycardia can come from the top two chambers of the heart (superventricular tachycardia) or the bottom two (ventriclular tachycardia).

As a general rule, supraventricular tachycardia (SVT) can be uncomfortable but is rarely life threatening. While there are a number of non-life threatening forms of ventricular tachycardias (VT), this can commonly be a fatal arrhythmia.

TMC has a sophisticated electrophysiology lab with one of only 175 stereotactic ablation systems found worldwide, and the only one in Southern Arizona.
