Effect of Qiangxin Fumai Granule (强心复脉颗粒) on electrophysiological functions of the sinoatrial node during ischemia-reperfusion of the right coronary artery in rabbits
摘要
To study the effect of the Chinese medicine Qiangxin Fumai Granule (强心复脉颗粒
QFG) on electrophysiological functions of the sinoatrial node during ischemia-reperfusion (IR) of the right coronary artery in rabbits. The right coronary artery IR model in rabbits was adopted. The modeled rabbits were randomly divided into 4 groups: the model group
the atropine group
the high-dose QFG group
and the low-dose QFG group
with 8 animals in each group. In addition
twelve rabbits were selected for the sham-operative group. The drugs were administered once via duodenal perfusion after modeling had been stabilized for 10 min. The changes in AA interval
the sinoatrial conduction time (SACT)
the sinus node recovery time (SNRT)
the corrected sinus node recovery time (CSNRT) and the index of sinus node recovery time (ISNRT) at different time points during ischemia and reperfusion were measured. The AA interval was prolonged for more than 40 ms in the model group during ischemia. Compared with the model group
the four electrophysiological parameters abovementioned in the high-dose QFG group and the low-dose QFG group were decreased to different extents at each time point (P<0.01 or P<0.05)
and no statistically significant differences were found between the QFG groups and the atropine group (P>0.05). QFG is beneficial for accelerating the recovery of sinus node autorhythmicity and conduction function
so as to protect electrophysiological functions of the sinoatrial node. Accelerating the recovery of autorhythmicity and conduction function in the sinus node is considered its electrophysiological mechanism in the treatment of sinoatrial node injury induced by ischemia.
