BACKGROUND: In @entity1 undergoing coronary artery bypass surgery (CABGS), occurrence of @entity955 ( @entity955 ) is common in the postoperative period and is associated with increased morbidity with longer intensive unit care (ICU) and hospital stay. Prevention with antiarrhythmic drugs is of limited success and associated with significant side effects. Therefore alternative approaches, such as Bachmann Bundle pacing, are required. METHODS AND RESULTS: 154 consecutive @entity1 , mean age 58  8.8 years, including 134 males and 20 females, were randomized to three groups; Group I : No pacing n= 54, Group II : RA pacing n= 52, Group III : Bachmann Bundle pacing n= 48. All the groups were well matched with regard to age, left atrial size, ejection fraction and use of beta blockers. @entity1 in Groups II and III were continually paced at a rate of 100 beats per minute (bpm) or at 10 bpm more than @entity1 ' intrinsic heart rate. All the @entity1 were monitored for 72 hours by telemetry and occurrence of @entity955 was noted. Incidence of @entity955 was 0% (none of 48 @entity1 ) in Group III as compared to 16.6% in Group I (9 of 54 @entity1 ) (p 0.003) and 12.5% in Group II (5 of 52 @entity1 ) (p 0.03). There was a trend towards shorter ICU stay in Group III (3.9 days) as compared to Group II (4.5 days) and Group I (4.1 days). Among the three groups, the reduction in mean P wave duration also was greater in Bachmann bundle paced group. CONCLUSION: In @entity1 undergoing CABGS, Bachmann bundle pacing is superior to right atrial / no pacing in the post operative period for preventing occurrence of @entity955 and reducing ICU stay, commensurate with a reduction in mean P wave duration on surface ECG.
