To assess complications of single chamber pacemaker VVI.
We reviewed the medical files of 278 patients implanted with VVI pacemaker at Saint Joseph Hospital, Bawchrieh, Lebanon, between 1978 and 1988. We looked for complications that have been reported by the patients. We compared these complications to different factors: age, indication, retrograde conduction ECG aspect before implant.
36 patients (12.9%) reported at least once one of these complications: fatigue, headache, neck pain, palpitations, confusion, dyspnea, angina, chest pain, pulmonary oedema, pedal oedema, atrial fibrillation, cerebrovascular accident. These complications were more frequent when the indication was an atrial disease compared to AV Block. The retrograde conduction was frequent in patient with complications. Heart failure was aggravated by stimulation, but not induced by it.
The single chamber VVI is complicated by symptoms which could be minor, moderate and major. VVI is an acceptable mode of stimulation when the indication is AV block. The dual chamber pacemaker should consider the cost-effectiveness.
评估单腔VVI起搏器的并发症。
我们回顾了1978年至1988年间在黎巴嫩巴克里耶圣约瑟夫医院植入VVI起搏器的278例患者的病历。我们查找患者报告的并发症。我们将这些并发症与不同因素进行比较：年龄、适应证、植入前逆行传导心电图表现。
36例患者（12.9%）至少报告过一次以下并发症：疲劳、头痛、颈部疼痛、心悸、意识模糊、呼吸困难、心绞痛、胸痛、肺水肿、足部水肿、心房颤动、脑血管意外。与房室传导阻滞相比，当适应证为心房疾病时，这些并发症更常见。有并发症的患者中逆行传导很常见。心力衰竭因刺激而加重，但不是由刺激诱发的。
单腔VVI起搏器存在可能为轻微、中度和重度的症状并发症。当适应证为房室传导阻滞时，VVI是一种可接受的刺激模式。双腔起搏器应考虑成本效益。
