Abstract
In 50 patients under local anesthesia we have investigated, electrocardiographic changes in peritoneal insufflation of room air during peritoneoscopy. 1) There is no significant variance in pulse rate during 3 phases (before insufflation, after insufflation, after deflation). However, there are occasional cases of vagotony after insufflation, which may easily lead to circulatory insufficiencies. 2) There is some variance in the QRS vector, the T vector, the cardiac position and the transitional zone due to cardiac oppression; this cardiac oppression is caused by elevation of the diaphragm due to peritoneal insufflation of room air. 3) We observed that the supraventricular premature beat or the ventricular premature beat in 6 of 7 cases diminised after peritoneal insufflation of room air. 4) ECG monitoring is very useful to find early circulatory insufficiency during peritoneoscopy.
