文摘目的:通过病例回顾性调查来了解脊髓损伤患者窦性心动过缓的发生率,探讨这一特殊人群可能的心律失常风险及治疗策略。方法:对中国康复研究中心2004年1月～2009年12月年因脊髓损伤入院进行康复治疗的1 831例患者(男1 470例,女361例)进行入院后静息心电图调查,并记录心率及心律失常类型。结果:颈脊髓损伤患者平均心率显著低于胸腰段脊髓损伤患者(男:67次/min vs 74次/min,女:67次/min vs 76次/min,P<0.01),窦性心动过缓发生率显著升高(男:34%vs 10%,女:29%vs 8%,P<0.01)。结论:脊髓损伤康复期患者中,窦性心动过缓主要发生于颈脊髓损伤患者。目前长期药物治疗效果尚不清楚,对难治性、持续性严重心动过缓者起搏器治疗可能是有益的选择。需要进一步循证医学证据支持。
