本文报道24例病态窦房结综合征(简称病窦),22例窦性心动过缓(简称窦缓)和6例可疑病窦患者,分别测定窦房结恢复时间(SNRTm)、校正窦房结恢复时间(SNRTc)、窦房结恢复时间指数(SNRTi)、实测固有心率(IHR_0)、窦房传导时间(SACT)、动态心电图、阿托品试验及下蹲运动试验的结果。通过对各自的真阳性、假阴性、真阴性和假阳性率分析,表明动态心电图、SNRTm、SNRTc、SNRTi对诊断病窦有较高的特异性及敏感性;IHR_0、阿托品试验及运动试验对探讨病窦的进一步分型有所帮助。
This article reports 24 cases of sick sinus syndrome (Sick sinus), 22 cases of sinus bradycardia (sinus slow) and 6 cases of suspected sick sinus, were measured sinoatrial node recovery time (SNRTm), correction of sinoatrial (SNRTc), SNRTi, IHR_0, SACT, Holter, atropine test and squat exercise test. Through the analysis of their true positive, false negative, true negative and false positive rate, the dynamic electrocardiogram, SNRTm, SNRTc and SNRTi have higher specificity and sensitivity for the diagnosis of sick sinus; IHR_0, atropine test and exercise test Sick sinus further classification helpful.
