An<unk>  <unk>  is one of a number of tests of the electrical conduction system of the heart performed by a cardiac<unk> t, a specialist in the electrical conduction system of the heart.  These tests are performed using catheters situated within the heart.
There are a number of different tests that fall under the heading of an<unk>  (EP<unk> .  If the heart is electrically stimulated via the intracardiac catheter it is known as programmed electrical stimulation (PES).  PES is used to help diagnose and risk stratify individuals with a number of rhythm disturbances of the heart.  Other<unk> es that do not require extrinsic stimulation of the heart include conduction<unk> es to determine if the individual's heart block is at risk of progressing to complete heart block.
EP<unk> es also allow the ablation of ectopic electrical foci causing supraventricular arrythmias
