We report a prospective and descriptive study in 12 patients who had pacemaker implantation from may. 1996 and dec. 1997. Our patients benefited from complete clinical examination, ECG (12 derivations), standard laboratory tests, chest X ray. Pulsed-Doppler, two dimensional and TM echocardiography have been performed. Stimulation was achieved using endocardial lead introduced percutaneously. During the study, 12 patients over 22, representing 55% of the subjects with symptomatic conduction defects, had definitive pacemaker implantation. Mean age was 53.8 years +/- 18. Most of the patients lived in Dakar. Sex-ratio was 0.58 (7 males/5 females). Most of the patients (83%) had low socio-economical status. Before implantation mean heart rate was 47 bpm +/- 20.8. Mean blood pressure was 155 mmHg +/- 26.7 (systolic) and 71.6 +/- 20.8 mmHg (diastolic). Heart failure was present in 5 patients/12. Others symptoms were mainly syncope (83%). Mean cardiothoracic ratio was 0.56 +/- 0.09. Over a 14 months period we have implanted 7 double chamber stimulators (DDD) and 5 monochamber (VVI). Over a 210 days follow-up, main problems are infection of the pocket in 2 patients. In one of them culture was positive. In Senegal, it is necessary to develop cardiac stimulation. Pacemakers should be available for all patients with symptomatic conduction defects. A national center for electrophysiologic studies and pacemaker implantation is a priority.
我们报告了一项针对1996年5月至1997年12月期间接受起搏器植入的12例患者的前瞻性描述性研究。我们的患者接受了全面的临床检查、心电图（12导联）、标准实验室检查、胸部X光检查。进行了脉冲多普勒、二维和经食管超声心动图检查。通过经皮插入心内膜导线实现刺激。在研究期间，12例年龄超过22岁的患者，占症状性传导缺陷患者的55%，接受了确定性起搏器植入。平均年龄为53.8岁±18岁。大多数患者居住在达喀尔。性别比为0.58（7例男性/5例女性）。大多数患者（83%）社会经济地位较低。植入前平均心率为47次/分钟±20.8。平均血压为收缩压155 mmHg±26.7和舒张压71.6±20.8 mmHg。12例患者中有5例存在心力衰竭。其他主要症状为晕厥（83%）。平均心胸比为0.56±0.09。在14个月的时间里，我们植入了7台双腔起搏器（DDD）和5台单腔起搏器（VVI）。在210天的随访期间，主要问题是2例患者出现囊袋感染。其中1例培养结果为阳性。在塞内加尔，有必要开展心脏刺激治疗。对于所有有症状性传导缺陷的患者都应提供起搏器。建立一个国家电生理研究和起搏器植入中心是当务之急。
