RT Journal Article SR Electronic A1 Mosley, Mary T1 Botulinum Toxin Reduced AF Burden, Heart Rate Variability at 1 Year in Pilot Study JF MD Conference Express YR 2015 FD SAGE Publications VO 15 IS 12 SP 10 OP 11 DO 10.1177/1559897715593726 UL http://mdc.sagepub.com/content/15/12/10.abstract AB Secondary analysis of a small pilot study has shown that botulinum toxin vs placebo reduces the burden of atrial fibrillation at 1 year after coronary artery bypass graft surgery. An improvement in heart rate variability also suggests that botulinum toxin injected into fat pads is a neuromodulator with effects on the autonomic nervous system.
