【摘要】：目的探讨不同类型心律失常患者CT冠状动脉造影(CTCA)图像质量和检查成功率的差异。方法前瞻性连续纳入符合入选和排除标准的心律失常患者795例(实验组),并按心律失常类型分为窦性、房性、房室交界性、室性、混合性5个亚组。另随机选择心律规整患者100例作为对照组。比较不同类型心律失常组患者的平均心室率、心率变异、需心电编辑比例、CTCA图像质量、可诊断节段、可诊断例数以及辐射剂量等的差异。结果窦性、房性、房室交界性、室性、混合性心律失常分别为59、246、110、222、158例。5个亚组与对照组之间在心率变异、需多期相重建、需心电编辑、可诊断节段、可诊断例数等的差异均有统计学意义(P0.05)。5亚组之间的比较显示,窦性心律不齐的检查成功率最高,混合性心律失常则最低,后者与房性、交界性、室性三组之间差异均有统计学意义(可诊断节段,χ~2=27.47,P=0.000;χ~2=63.27,P=0.000;χ~2=57.86,P=0.000)。结论心律失常类型对CTCA成功率有明显影响,混合性心律失常CTCA成功率最低,有必要对混合性心律失常患者进行CTCA检查前筛选或预治疗。
[Abstract]:Objective to investigate the difference in the image quality and success rate of CT coronary angiography (CTCA) in patients with different types of arrhythmia. Methods 795 patients with arrhythmia (experimental group) were prospectively integrated into 5 subgroups of sinus, atrial, atrioventricular borderline, ventricular, and mixed, according to the type of arrhythmia. 100 patients with arrhythmia were selected as the control group. The average ventricular rate, heart rate variation, the ratio of ECG editing, CTCA image quality, diagnosis of segment, diagnostic number and radiation dose were compared in the different types of arrhythmia groups. The results of sinus, atrial, atrial, ventricular, ventricular, and mixed arrhythmia were 59246,1, respectively. The heart rate variation between the 10222158.5 subgroups and the control group required multiphase reconstruction, requiring electrocardiographic editing, diagnosis of segments and the number of diagnostic cases (P0.05), the comparison between the.5 subgroups showed that the success rate of sinus arrhythmia was the highest and the mixed arrhythmia was the lowest, and the latter was with atrial, borderline, and room. The differences between the three groups were statistically significant (diagnostic section, X ~2=27.47, P=0.000; X ~2=63.27, P=0.000; X ~2=57.86, P=0.000). Conclusion the type of arrhythmia has an obvious effect on the success rate of CTCA, and the success rate of mixed arrhythmia CTCA is the lowest. It is necessary to select or pretreat the patients with mixed arrhythmia before the CTCA examination.
