摘要(Abstract):

本文对30名健康老年人和12例老年病窦患者(年龄60~75岁)在自主神经阻滞(静注阿托品和心得安)前后作经食道心房调搏和固有心率(IHRo)测定,并与中年组作对照。结果发现:自主神经阻滞后测得的窦房结恢复时间和校正窦房结恢复时间对诊断老年人病窦的敏感性和准确性比阻滞前大大提高(敏感性由66.67%提高到100%,准确性由88.1%提高到97.63%),而特异性不变(均为96.7%)。用 IHRo/IHRp-2SD<1诊断老年人病赛的特异性达100%,准确度也高(85.71%),但敏感性较低(50%)。在老年人中应用自主神经阻滞方法安全可行。
Transesophageal atrial pacing was performed and the sinus node recovery time(SNRT),the corrected SNRT(CSNRT)and the intrinsic heart rate (IHR_0)were obtained in 30 healthy elderly subjects and 12 elderly patients (over 60 years)with Sick Sinus Syndrome(SSS)before and after autonomic blockade by administering atropine and propraonlol,i,v.Twenty-eight healthy subjects and 30 patients under 60 years were also studied for comparison.The results showed that SNRT and CSNRT obtained after blockade had much higher sensitivities and accuracies for SSS than those obtained before(100% vs 66.67% for sensitivities,97.62% for accuracies),and had the same specificities(96.67%) both before and after blockade.IHRo/IHRp-2SD<1 had a specificity of 100% and an accuracy of 85.71% for SSS,although the low sensitivity(50%).
