Combined automatic implantable cardioverter-defibrillator and pacemaker systems: Implantation techniques and follow-up

摘要: The automatic implantable cardioverter-defibrillator (AICD) effectively prevents death due to ventricular tachycardia or fibrillation. Some patients who need an AICD also require cardiac pacing treat symptomatic bradycardia, bradycardia after defibrillation, provide a rate floor reduce the frequency of bradycardia-related arrhythmias. can benefit from antitachycardia pacing. A mapping technique implant pacemaker and sensing leads is presented. For with later AICD, left ventricle mapped use rate-sensing electrodes identify site at which minimal stimulus maximal electrogram amplitudes are recorded. An external that has amplifiers similar those in used monitor electrogram. implanted implantation undertaken by right lead while standby mode; beep then determine where detection does not occur. Eight underwent combined AICD-pacemaker system (four pacemakers, three demand pacemakers one atrial pacemaker). Neither inhibition arrhythmia nor double counting occurred. Satisfactory function was shown all postoperatively, no malfunction observed. Thus, currently available technology, be satisfactory both devices without adverse device-device interactions.
