[Diagnosis of endocardial electrode microdislocation at endocardial pacing]. / K voprosu diagnostiki mikrodislokatsii éndokardial'noí élektricheskoí stimuliatsii serdtsa.

Signs of microdislocation of an endocardial electrode (EE) were observed in 56 (14.4%) of 390 patients with an implantable pacemaker in the postoperative period. The microdislocation was diagnosed from electrocardiographic evidence for no response of a pacing pulse and from fluctuations in the pacing threshold, and from X-ray findings of the thickened and ill-defined outlines of a distal EE with preserving cardiac stimulation. The microdislocation preserves high parameters, as evidenced by a PM-20 M digital analyzer.

[The runaway pacemaker syndrome during electrical ventricular stimulation of the heart]. / Sindrom "ubegaiushchego élektrokardiostimuliatora" pri élektricheskoi zheludochkovoi stimuliatsii serdtsa.

The paper reports a case of escaping pacemaker syndrome in a female with continuous endocardial ventricular pacing. The syndrome was provoked by defects in the electronic scheme because of weakening of pacemaker's battery.

The authors consider that puncture decompression of the intervertebral disc with using the endoscopic technique and laser evaporation is a method allowing to rapidly and effectively help patients with the root syndrome. All the manipulations are made with local anesthesia. The patients started walking on the second day after operation.

[Fixation of the endocardial electrode in cardiac pacing]. / K voprosu fiksatsii éndokardial'nogo élektroda pri élektricheskoi stimuliatsii serdtsa.

The late outcomes of continuous endocardial pacing surgery were studied in 34 patients when various approaches were used to fix a proximal endocardial electrode. When fixed to a vein or its adjacent tissues, the electrode remained to be stable while raising hands. When fixed to the cephalic vein, this procedure was accompanied by the displacement of the endocardial electrode and the appearance of X-ray signs of electrode instability. The new procedure for fixing the proximal electrode contributes to the stability preservation of the intracardiac part of an endocardial electrode.

The X-ray films and ECG records were analysed in 11 cases of dislocation and 20 cases microdislocation of the endocardial lead in patients with monopolar ventricular pacing. In 3 patients lead was dislocated into the right ventricle cavity, in 2 patients--in the another heart cavity, in 6 cases lead dislocation was negligible. In 20 cases of microdislocation the fluctuation all intracardiac parts of the endocardial lead not only his distal end was revealed. Therefore it is better to call this complication of heart pacing "the endocardial lead instability". The X-ray picture of the negligible lead dislocation was identical to microdislocation: a thickening unclear contour of the distal lead end. The ECG picture in cases of dislocation was different from microdislocation: the lack of pacing contrary to pacing preserved in cases of microdislocation. All patients with dislocation and microdislocation had high amplitude spike of pacemaker impulses.
