[Experience with the implantation of sensory multiple programmable pacemakers of the Siemens firm].

The paper summarizes the experience on 27 implantations of sensory multiprogrammable pacemakers (two-chamber Synchrony-II and one-chamber Sensolog-III) produced by Siemens-Elema. The implantations were performed in the Moscow Cardiostimulation Center in 1993. Primary pacemaker implantation was performed in 19 patients, 8 patients needed the replacement of one-chamber pacemakers because of the power source exhaustion or circulatory insufficiency. The two-chamber pacemaker was implanted to 14 patients with a complete AV-block and chronotropic sinus node incompetence and to 4 patients with sick sinus syndrome in intact AV-conduction. In 6 patients the one-chamber pacemaker was implanted to stimulate the right ventricle. They had permanent bradysystolic auricular fibrillation and complete AV block with persistent or transitory tachysystolic auricular fibrillation. 3 patients with sick sinus syndrome received one-chamber pacemaker. The authors think their experience with sensory Siemens-Elema pacemakers positive.
