摘　　要：心脏冠状动脉CT(心脏CT)检查是将碘造影剂注射入血管进行造影的医学检查技术,心血管内科医生可根据影像对心脏冠状动脉的堵塞和血流速度作出诊断。检查之前,患者需保持稳定的心率,一般要求每分钟不高于60次,如心率过快可利用β-受体阻滞剂、硝酸甘油等药物进行降低。此技术检查时间短、副作用小、漏检率和误检率很低。Cardiac CT,or coronary CT,is a medical imaging technique that involves injecting iodine contrast agents into blood vessels to visualize the heart’s coronary arteries.Cardiovascular specialists utilize these images to diagnose coronary artery blockages and assess blood flow velocity.Prior to the examination,patients are required to maintain a stable heart rate,typically not exceeding 60 beats per minute.Medications such asβ-receptor blockers and nitroglycerin may be administered to reduce heart rate if necessary.This technology offers rapid imaging,minimal side effects,and low rates of false negatives and false positives.

关 键 词：心脏CT Β-受体阻滞剂 碘化造影剂 硝酸甘油
