目的 评价右心室流出道间隔部起搏临床应用的有效性及安全性.方法 将所入选患者按右心室起搏电极置入部位随机分为被动固定导线心尖部(常规组)和螺旋电极起搏右心室流出道间隔部(非常规组),比较两组患者在术中及术后起搏参数变化及不良反应情况.结果 非常规组在术中测试起搏阈值及电流明显高于常规组,但术后1个月差异无统计学意义;术中阻抗及R波振幅二者无明显差异.非常规组起搏时QRS时限较常规组明显要窄,但差异无统计学意义.无患者发生不良反应.结论 选择性部位起搏的临床应用安全、有效.
目的 評價右心室流齣道間隔部起搏臨床應用的有效性及安全性.方法 將所入選患者按右心室起搏電極置入部位隨機分為被動固定導線心尖部(常規組)和螺鏇電極起搏右心室流齣道間隔部(非常規組),比較兩組患者在術中及術後起搏參數變化及不良反應情況.結果 非常規組在術中測試起搏閾值及電流明顯高于常規組,但術後1箇月差異無統計學意義;術中阻抗及R波振幅二者無明顯差異.非常規組起搏時QRS時限較常規組明顯要窄,但差異無統計學意義.無患者髮生不良反應.結論 選擇性部位起搏的臨床應用安全、有效.

Objective To compare the safety and efficiency of pacing at right ventricular outflow versus right ventricular apex. Method Patients were divided into two groups: pacing at ventricular cardiac apex (common pacing group, n = 22) and pacing at right ventricular outflow tract(uncommon pacing group, n = 18). Results Impedance and amplitude of R-wave were similar during implantation between the two groups (all P 0. 05). The pacing threshold and electric current were significant higher in uncommon group than those in common pacing group ( all P < 0. 05), however, these differences disappeared at 1 month post pacemaker implantation ( all P 0.05). The mean QRS duration tended to be shorter in uncommon pacing group compared to that in common pacing group (P 0.05 ). There was no pacemaker associated adverse effect in both groups. Conclusion The safety and efficiency of pacing at right ventricular outflow was similar as those of pacing at right ventricular apex.
