窦房结功能不应期(SNERP)是反映窦房结兴奋性的重要指标。1980年 Kerr 等测定了兔离体窦房结不应期,1983年 Kerr 利用心内程控刺激成功地用于临床。研究表明,SNERP 测定可提高病窦诊断的敏感性和特异性。1986年以来,国内也相继有类似的报告。为了进一步探讨SNERP 测定临床意义,提高病窦的诊断率,我们在自主神经阻滞下对病窦和正常人进行了测定,现报告于下。研究对象和方法正常对照组18例(男15,女3例),平均年龄42.9岁,其中2例为无症状性单纯窦缓,均经查
Sinus node Functional refractory period (SNERP) is an important indicator of sinus node excitability. In 1980, Kerr et al. Determined the sinus node refractory period in rabbits. In 1983, Kerr successfully used the program for intracardiac programmed stimulation in clinical practice. Studies have shown that the SNERP assay can improve the sensitivity and specificity of the diagnosis of sick sinus. Since 1986, there have been similar reports in China. In order to further explore the clinical significance of SNERP determination and to improve the diagnosis rate of sick sinus, we measured sick sinus and normal people under autonomic nerve block and are reported below. Subjects and Methods 18 cases of normal control group (15 males and 3 females), mean age 42.9 years, of which 2 cases of asymptomatic simple sinus slowly, were investigated
