Seguridad y eficacia clínica de la estimulación con el modo AAI en la disfunción del nodo sinusal: seguimiento a largo plazo

Pacing mode survival in patients with single chamber atrial pacemaker for sinus node dysfunction

“…In this study, 2 of the 4 had underlying right bundle branch block at the time of implantation. Similar results were reported by Morinigo et al 14 (0.8 % per year) and Kim et al 4 (0.9 % per year). Mean age in their cohorts were 72yrs and 59yrs respectively.…”

“…However, lead failure was twice as frequent with DDDR (22.8 %) than with AAIR pacing (13.7 %). Nielsen et al 7 and Morinigo et al 14 reported reoperation rate of 4.7 % and 4.3 % for lead failures. The possible reasons were not reported by them.…”

“… 12 Our findings of a mean age of 55.6 ± 12.7 years in our study is in agreement with this data that patients in India and other developing countries are significantly younger than those in the West. 5 , 7 , 13 , 14 …”

“…The superiority of AAIR pacemaker over VVIR pacemaker was shown in previous studies, with a lower incidence of heart failure, atrial fibrillation, thromboembolism, stroke and death. 1 , 2 , 12 , 14 The choice between AAIR vs DDDR is still debated. Prospective studies by Masumoto et al 15 from Japan and Kim et al 4 from Korea with follow up over 5 yrs have shown AAIR pacing is safe compared to dual chamber pacing and was associated with less lead related complications 15 and chronic atrial fibrillation.…”
