Perioperative myocardial ischemia and infarction. Detection of myocardial ischemia using continuous electrocardiography.
Continuous ECG recording of ST segments can provide important insight into the effects of CAD in patients before, during, and after anesthesia and surgery. The stresses of anesthesia and surgery are particularly threatening to the patient with critical coronary disease and ischemia. ST-segment monitoring is a useful alternative to preoperative stress ECG in patients who are unable to exercise, particularly if radionuclide techniques are not readily available. Continuous ST-segment monitoring provides an additional and unique method of monitoring patients during and after surgery, and on-line analysis of such data provides the anesthesiologist with opportunities to recognize and promptly respond to ischemic episodes. Future studies will determine whether such aggressive strategies will alter the outcome for patients with perioperative myocardial ischemia.
