[Clinical experience with the first 100 operations to implant programmed electrocardiostimulators]. / Klinicheskii opyt pervykh 100 operatsii implantatsii programmiruemykh élektrokardiostimuliatorov.

The implantation of a home programmed device "ECS-500" was performed in 121 patients with different disturbances of the cardiac rhythm. Programmed ECSs were used in 103 patients with echocardiography and integral rheography. Seventy six patients were observed in terms from 2 months to 1.5 year. Optimum frequencies of electrostimulation (ES) were determined for different groups of patients. Lower frequencies of ES allowed to lessen manifestations of angina pectoris in patients with ischemic heart disease. Higher amplitude of the impulse prevented reoperations in 4 patients with "block of output" of electrodes. The experience allows "ECS-500" to be recommended for introduction into clinical practice.

[Physiologic electrostimulation of the heart ventricles in disorders of atrioventricular conduction]. / Fiziologicheskaia elektrostimuliatsiia zheludochkov pri narusheniiakh atrioventrikuliarnogo provedeniia.

Thirty-two patients with disturbed atrioventricular conduction underwent operation for continuous P-wave electrostimulation (ES) with implantation of Soviet-made serial KC-320 apparatuses by the myocardial (28 patients) and endocardial (4 patients) methods. The patients were examined in postoperative periods of 3 to 15 months. Stable bio-controlled ES with a good clinical result was recorded in 29 patients, dislocation of the atrial endocardial electrode--in one patient; the development of frequent paroxysms of atrial flutter-fibrillation made it necessary to change the ES regimen. The authors' experience allows KC-320 to be recommended in wide clinical practice.

[Surgery of the heart conduction system in Leningrad: experience with 3000 operations]. / Khirurgiia provodiashchikh putei serdtsa v Leningrade: opyt 3000 operatsii.

The authors make an analysis of the experience with 3239 operations for different disturbances of heart rate. Recommendations are given for different kinds of electro-stimulation.

[Experience in using transesophageal electrocardiostimulation in emergency heart rhythm disorders]. / Opyt primeneniia chrespishchevodnoi élektrokardiostimuliatsii v urgentnoi kardioritmologii.

The paper is concerned with the results and analysis of transesophageal electrocardiostimulation in 383 patients before and in hospital over 6 years for urgent therapy of brady- and tachyarrhythmias. The method was assessed using a simple, recoverable and effective first aid element in combined resuscitation measures, in therapy of paroxysms of supraventricular tachycardia, in patients with the sinoatrial node weakness syndrome during cardioversion and narcosis, in primary and repeated pacemaker implantations, in acute myocardial infarctions complicated by bradyarrhythmias. Transesophageal electrocardiostimulation in urgent therapy of bradyarrhythmias, the sinoatrial node weakness syndrome, disorders of permanent electrocardiostimulation with fits of Morgagni-Adams-Stokes syndrome is an uncomplicated method of choice and a stage before temporary endocardial and permanent electrocardiostimulation.

[Clinical evaluation of continuous myocardial electrostimulation of the atria in the sick sinus syndrome]. / Klinicheskaia otsenka postoiannoi miokardial'noi élektrostimuliatsii predserdii pri sindrome slabosti sinusovogo uzla.

Forty-four patients with the syndrome of pacemaker weakness were subjected to the operation of the continuous electrostimulation of the right atrium from the infrasternal access using sutureless electrodes. Patients with grave attendant diseases were shown to benefit from this procedure. The use of Soviet commercially available sutureless electrodes makes it possible to considerably simplify the main stage of the operation and to ensure the reliable functioning of the biocontrolled cardiostimulators at the long-term postoperative period.
