Liaoning down-producing goats introduced into Qinghai province were used to trace and analyse the electrocadiograms ( ECG) on three bipolar chest leads. 对34只引入青海的辽宁绒山羊3个双极胸导联心电图进行了描记和分析。
Objective To investigate the electrocardiogram parameters of bipolar chest leads in 83 cases normal men. 目的探讨正常人ECG双极胸导联(BCL)心电图各参数值变化。
Objective: A prospective study was undertaken to evaluate both atrial and ventricular bipolar tined steroid eluting leads in long term dual chamber pacing. 目的:观察激素释放电极对心房和心室起搏阈值长期的影响,检验激素释放电极能否用来长期低能量安全的进行双心腔起搏。
Methods Electrograms of high right atrium, His bundle, coronary sinus and bipolar esophageal leads were simultaneously recorded, and the relations between right and left atrial potentials recorded by esophageal lead were analysed. 方法心内电生理检查时同步记录高位右心房、希氏束、冠状静脉窦和双极食管导联心电图,分析食管导联中右心房电位和左心房电位的关系。
