Permanent ventricular pacemakers. Comparison of transthoracic and transvenous implantation.
In the series of 86 patients with the Stokes-Adams syndrome or with symptomatic bradycardia managed with permanently implanted ventricular pacemakers reported on, 35 patients had primary implantation of epicardial leads at thoracotomy and 51 had transvenous endocardial electrodes passed via the jugular venous system for permanent ventricular pacing. The transvenous method of permanent pacemaker...
متن کاملIntrapleural permanent pacemakers in infancy.
Although treatment with permanent pacemakers has been extensively described in adults, there is little information about it in infants. Conventional sites for pacemaker implantation are the abdominal wall, subpectoral muscle region, subdiaphragmatic area, and the pelvic cavity. If the infant has a thin chest and abdominal wall, implantation of the pacemaker there produces an unsightly bulge and...
متن کاملHierarchy of ventricular pacemakers.
To characterize the pattern of pacemaker dominance in the ventricular specialized conduction system (VSCS), escape ventricular pacemakers were localized and quantified in vivo and in virto, in normal hearts and in hearts 24 hours after myocardial infarction. Excape pacemaker foci were localized in vivo during vagally induced atrial arrest by means of electrograms recorded from the His bundle an...
متن کاملAutopsy findings with permanent pervenous pacemakers.
Of 130 patients who received permanent pervenous pacemakers in the last 2 years at the Massachusetts General Hospital, 21 have died; complete postmortem data are available on seven who died 5 days to 18 months after insertion of the pacemaker. No deaths were related to pacemaker malfunction. No patient received routine anticoagulant therapy. The intracardiac portions of all pacemaker electrodes...
متن کاملVentricular-triggered pacemakers: clinical experience.
It is now generally agreed that the presence of symptoms is an indication for long-term pacing of patients with complete heart block, and that this treatment lowers the mortality considerably (Chardack et al., 1966; Sowton, 1967a). An appreciable proportion of paced patients has intermittent atrioventricular conduction so that if a fixed rate pacemaker is implanted there is competition between ...
