摘要
目的探讨双源CT冠状动脉成像和心电编辑在房颤患者中的应用价值。资料与方法应用双源CT对87例房颤患者行冠状动脉血管成像。对冠状动脉图像质量按4分法进行分段评价。将图像质量分值低于1分或连续两段2分者纳入需要心电编辑组。比较无需编辑组和需要编辑患者平均心率、心率波动和心率变异。结果对87例共1218段动脉进行图像质量评价。42例无需心电编辑,45例需心电编辑,两组平均心率、心率波动和心率变异之间的差异有统计学意义(P<0.01)。心电编辑后,有36例(80%)达到诊断要求。结论通过选择适当的重组时相,双源CT对部分房颤患者能直接获得满意的冠状动脉图像。心电编辑能够明显改善房颤患者冠状动脉CT血管成像图像质量。
Objective To evaluate the value of coronary angiography by dual-source CT and ECG editing in patients with atrial fibrillation.Materials and Methods 87 patients with atrial fibrillation（AF）underwent dual-source CT（DSCT）without β-blocking agents.Coronary image quality was evaluated by four-score method.The patients were divided into ECG-editing group,whose image quality was 1 score in one segment or 2 score in two continuous segments.Average heart rate,heart rate range and heart rate variability were recorded.Results In 87 patients,a total of 1218 segments were analyzed.ECG-editing was not needed in 42 patients,and ECG-editing was needed in 45 patients.The difference of average heart rate,heart rate range and heart rate variability between ECG-editing group and no ECG-editing group was very significant difference（P〈0.01）.After ECG-editing,good image quality in 36（80%）patients was obtained.Conclu-sion Good image quality can be obtained directly by dual-source CT in some patients with atrial fibrillation.ECG-editing can improve image quality of coronary angiography significantly.
