Permanent pacemaker implantation is a life-saving procedure that is performed worldwide. There is paucity of reports on pacemaker surgery in Nigeria. The aims of the study were to determine the indications for pacemaker insertion, the demographic distribution of the patients requiring it, the electrocardiographic (ECG) changes, and the management challenges in Nigeria.
One hundred consecutive patients who had pacemaker insertion done by our team from 1999 were included in the study. The patients' biodata, indications for pacemaker insertion, ECG changes, and the treatment profile were recorded.
There was female preponderance (93.0%) among the patients studied. Third-degree heart block was the indication in 86.0% of the patients and most patients did well with single lead ventricular pacing which is generally cheaper than the dual chamber pacing.
The majority of bradyarrhythmia patients in this environment can be maintained on single lead ventricular pacemaker.
永久性起搏器植入术是一项在全球范围内开展的挽救生命的手术。尼日利亚关于起搏器手术的报道较少。本研究的目的是确定起搏器植入的适应证、需要植入起搏器患者的人口统计学分布、心电图（ECG）变化以及尼日利亚的管理挑战。
本研究纳入了1999年以来由我们团队进行起搏器植入的100例连续患者。记录患者的生物数据、起搏器植入适应证、心电图变化及治疗情况。
在研究的患者中女性占多数（93.0%）。86.0%的患者适应证为三度房室传导阻滞，大多数患者采用单腔心室起搏效果良好，单腔心室起搏通常比双腔起搏便宜。
在这种环境下，大多数缓慢性心律失常患者可采用单腔心室起搏器维持治疗。
