Effects of Biatrial Pacing in Prevention of Postoperative Atrial Fibrillation After Coronary Artery Bypass Surgery

Abstract

Biatrial overdrive pacing is more effective in preventing post-CABG AF than single-site atrial pacing; this therapy also results in a shortened hospital stay. The overall reduction in atrial activation time with BiA pacing was reflected in the reduction in P(dis).

Interventions on Prevention of Postoperative Atrial Fibrillation in Patients Undergoing Heart Surgery

“…[51][52][53][54][55][56][57][58][59][60][61] These trials were small, varying in size of treatment groups from 9 to 100 patients. Treatment protocols used different locations of pacing electrodes (right atrial, 51-57 left atrial, 54,57 and biatrial pacing. [53][54][55][56][57][58][59][60] ).…”

“…Treatment protocols used different locations of pacing electrodes (right atrial, 51-57 left atrial, 54,57 and biatrial pacing. [53][54][55][56][57][58][59][60] ). Trials also differed in pacing algorithms; some used simple overdrive at a fixed heart rate, 53,55,59 and others used more complex overdrive algorithms.…”

“…The incidence of postoperative stroke was available for 14 of 52 trials. 9,13,28,33,37,[41][42][43][44][45][46]48,54,59 These trials represented data for 2877 of a total of 8122 patients randomized (35%). In these studies, the percentage of patients with AF was reduced from 38.6% in the control group to 23.7% in the treatment group (OR, 0.38; 95% CI, 0.28 to 0.52), which is similar to the overall estimate.…”

Influência da estimulação biatrial temporária externa na prevenção da fibrilação atrial no pós-operatório de revascularização miocárdica sem circulação extracorpórea

“…According to literature, several studies conducted with single and biatrial pacemakers (with a variety of algorithms) have been published showing results generally favourable for reducing the incidence of atrial fibrillation in the period after myocardial revascularization 7,[12][13][14][27][28][29] . This was demonstrated in this study in which the presence of atrial fibrillation in the control group (with no artificial stimulation) was 36.73%, and in the therapeutic group (with artificial stimulation) it was 14.29%, with high statistical significance (p = 0.0194).…”

Effectiveness of triple-site triggered atrial pacing for prevention of atrial fibrillation after coronary artery bypass graft surgery

“…[20][21][22][23] Recently, several reports have shown that multisite temporary atrial pacing via epicardial electrodes placed during surgery might be effective in preventing postoperative AF. [24][25][26][27][28][29][30][31][32] In a double-blind, randomized study, Daoud et al evaluated the effects of different pacing modes in 118 patients who had undergone open heart surgery. 28 In this study, patients were randomized to one of the following three groups: right atrial pacing with an inhibited mode at a rate of 45 beats/min; right atrial overdrive pacing with a triggered mode ≥ 10 beats greater than the patient's intrinsic (but not < 85 beats/min) rate; and biatrial overdrive pacing with a triggered mode ≥ 10 beats greater than the patient's intrinsic (but not < 85 beats/min) rate.…”
