Abstract:
Objective To study the effects of intrinsic ganglionated plexi on the susceptibility to atrial fibrillation(AF)in canines induced by rapid atrial pacing.Methods Atrial efficient refractory period(AERP)and the dispersion of AERP were obtained in 13 healthy mongrel dogs before paced at 600 bpm.The fat pads containing the ganglionated plexi located on the junction of right superior pulmonary vein and atrium in 7 dogs were excided(denervation group),while the fat pad in the other 6 dogs were kept(control group).The time for the emerge of sustained AF was recorded.Atrial efficient refractory period(AERP)and the dispersion of AERP were also determined.Results There was statistical difference in the time for the emergence of sustained AF.In denervation group,it took more time than the control group(120?67 h vs 80?52 h,P
