Electrocardiography

Abstract

The ECG remains the prime monitor for the detection of dysrhythmias or myocardial ischemia in the perioperative period. It is an inexpensive, easily applied, and easily interpreted monitoring system that can function throughout the operative period. No other single monitoring system can fulfill the ECG's function over such a wide range of clinical and surgical situations. Careful attention to detail in the calibration and lead selection and close attention to subtle repolarization changes make the ECG a versatile and adequate monitor of dysrhythmias and ischemia. Computer-assisted methods will continue to improve the sensitivity of this time-proved monitoring modality.
