【摘要】 目的探讨心电编辑技术在双源CT冠脉成像心律不齐患者中的应用。方法回顾性分析心律不齐影像53例(窦性心律不齐34例,早搏19例)。按心率波动范围分组,评价影像节段质量。对于影像节段显示为Ⅲ,Ⅳ级影像者进行心电编辑处理,比较编辑前后影像节段评级的变化。结果窦性心律不齐编辑前Ⅲ,Ⅳ级影像比例46.5%,编辑后下降到21.2%;早搏编辑前Ⅲ,Ⅳ级影像比例50.4%,编辑后下降到17.5%;心率波动范围越大,编辑后影像质量改善越明显。结论心电编辑技术可部分改善心律不齐影像的质量,对于严重心律不齐者,心电编辑效果不佳,属检查禁忌。更多还原

【Abstract】 Objective To explore the application of ECG editing technique on a rrhythmia imagings of coronary artery imaging with dual-source CT.Methods Retrospective analysed 53 cases with arrhythmia imagings(sinus irregularity 34 cases and bearing premature 19 cases.).grouping according to extension of heart-rate exchange,evaluated imaging-segments quality.Ⅲ and Ⅳ grade imagings would be deal with the methods of ECG editing and compared difference of pre-editing with after-editing.Results In sinus irregularity group,the imaging ratio in Ⅲ,Ⅳ grade was 46.5% before editing and was redused to 21.2% after editing;in bearing premature group,the imaging ratio in Ⅲ,Ⅳ grade was 50.4% before editing and was red used to 17.5% after editing;larger the extension of heart-rate was,more obviously the imaging quality was improved after editing.Conclusion partly cases of arrhythmia imagings would be improved through ECG editing technique.to the cases of arrhy thmia imagings in the extreme badly grade,imaging quality was not be improved efficiencyly by ECG editing,these partly cases would be belong to the scanning taboo.更多还原
