Automated ST-segment monitoring.

Automated ST-segment monitoring expands the ability of the anesthesiologist to detect ischemia intraoperatively. However, improvements in technology are required before significant advances in patient care and safety can be ascribed to such monitoring. Until then, the clinician must abide by the adage that monitoring is an extension of the physical examination and that data must therefore be interpreted in the context of the total clinical picture presented by the patient.
