| Abstract: | Objective This paper was to investigate the effect of different pacing sites in atrium on the electrophysiology of atrioventricular node(AVN) in isolated rabbit heart.Method Isolated rabbit hearts were constantly perfused using the mixture of equal volume of blood and Tyrode's solution via Langendorf apparatus.The perfused rabbit heart was paced from crista terminals(CT)and interatrial septum (IAS) and the electrophsiological parameters of AVN were recorded and analyzed,respectively.Results It was showed that when paced from both sites,electrophsiological parameters of AVN including AH interval,functional refractory period,Weckbech cycle length differentiated nonsignificantly.Conclusion Pacing from different sites in atrium has no effect on the electrophysiology of AVN in this animal mode. |
