title: [Intraoperative electrocardiographic control of the position of the cardiac part of the ventriculoatrial valve catheter].
abstract: The author reports 86 cases treated surgically at the Department of Neurosurgery, Medical Academy in Warsaw in the years 1974--1977 for hydrocephalus of different aetiology, who had Pudenz and Hakim valves implanted and in whom the position of the intracardiac part of the device was checked by ECG during the operation. The method included filling of the cardiac portion of the device with 10% saline and connecting it to the ECG on which the ECG curve was recorded continaually during insertion of the catheter into the venous system. Obtaining of P wave in the record corresponding in height to the QRS complex was a reliable indicator of the end part of the catheter reaching the middle part of the right atrium. The described method is technically simple and no complications have been observed as yet connected with it.
