ECG UNIT AND ITS APPLICATION TO FUNCTIONAL ENDOSCOPY

Abstract

The usefulness of ECG unit in functional endoscopy is discussed. ECG unit is an apparatus for getting good still images of electronic endoscope with decreasing the affecting of cardiac movement originally. Since it superimposes electrocardiogram upon TV monitor, we applied ECG unit to superimpose the recording of mucosal blood flow, pH and potential difference in addition to ECG. This application resulted in stable and effective measurements. The superimposing display of ECG also made the endoscopic surgery more safely in patient with cardiovascular diseases.
