A Look at Intracardiac Electrophysiology Studies (August 1997)

August 1997 pages 9-17 Coding Communication A Look at Intracardiac Electrophysiology Studies The heart pumps blood by muscular contraction. To perform this function, the heart must conduct electrical impulses that are carried through the heart via a specialized route known as the conduction system. (Fig. 1) The heart's electrical activity generates currents that spread to the skin. Therefore, electrocardiographic recordings (93000-93010) employ external skin electrodes to pick up electrical current identified by waveforms. ECG recordings represent the precise sequence of electrical events normally or abnormally occurring in the heart. Electrophysiology studies (EPS), however, give more detailed information about the...
