目的探讨64层螺旋CT冠状动脉成像过程中受检者呼吸配合模式,以期保证较好的图像质量,提高检查成功率。方法将1 000例冠状动脉疾病患者随机均分为对照组和观察组,对照组按常规实行健康教育和屏气法呼吸配合训练;观察组改为捏鼻法呼吸配合训练。结果观察组呼吸配合时间、一次检查成功率显著优于对照组(均P<0.01),心率波动>10次/min及室性早搏发生率显著少于对照组(均P<0.01)。结论捏鼻法呼吸模式能显著提高64层螺旋CT冠状动脉成像检查效率。
Objective To explore the breathing pattern of subjects during 64-slice spiral CT coronary angiography in order to ensure better image quality and improve the success rate of examination. Methods One thousand patients with coronary artery disease were randomly divided into control group and observation group. In the control group, health education and breath-hold breathing training were performed routinely. The observation group was changed to kneading nose-breathing training. Results The resuscitation time of the observation group was significantly better than that of the control group (P <0.01). The heart rate fluctuation> 10 beats / min and the incidence of ventricular premature beats were significantly less than those of the control group (all P <0.01). Conclusion The pinch nose breathing mode can significantly improve the efficiency of 64-slice spiral CT coronary angiography.
