摘　　要：目的 探讨不同风险组别急性肺动脉栓塞患者校正的Q-T间期离散度（Q-TCd）.方法 收集24h内入院确诊的78例肺动脉栓塞患者的心电图信息,根据欧洲心脏协会肺动脉栓塞指南将患者分成低风险、中等风险、高风险3组,计算心电图积分、Q-TCd.结果 高风险组Q-TCd较中、低风险组显著增加（94.5±30.1、68.1±19.8,58.6±22.3,均P＜0.01）.Q-TCd与肺动脉收缩压和心电图积分存在正相关（r=0.67、0.30,P＜0.01或P= 0.05）.结论 心电图Q-TCd 分析有助于肺动脉栓塞风险评估.Objective To investigate the association between Q-T dispersion and the severity of acute pulmonary embolism（APE）. Methods 78 patients with APE were classified into low, intermediate and high-risk groups. ECG scores and corrected Q-T interval dispersion （Q-Tcd） were measured on ECGs recorded within 24 hours of hospital admission. Results Q-Tcd was significantly higher in high-risk group than in low and intermediate-risk groups （94.5 ± 30.1, 68.1 ± 19.8, 58.6 ± 22.3, P〈0.01, respectively）. There was a moderate correlation between Q-Tcd and pulmonary artery pressure （r=0,67, P〈0.01） and a low correlation between Q-Tcd and ECG score （r=0.30, P=0.05）. Conclusion Q-Tcd analysis may contribute to APE risk assessment.
