本文将104例患者分为正常对照,窦缓和病窦征三组行电生理研究。SAE 和 Strauss程序刺激法测得 SACTi 和 SACTd 分别为:92.8±21.7,94.4±16.5;128.1±60.3.130±34.2;144.6±48.6,146.1±34·2(ms)。各组内两均值呈线性相关,均值差异无显著性。认为 SAE 法切实可行。当程序刺激对 SAN 自律和传导性显著影响时 SACTd 较为准确。由于 SACTi 受许多方法学因素影响,窦房正、逆传不等,则 SACTd 更接近真值。SACT 和 cSNRT 异常检出率及量值延长程度病窦组明显高于窦缓组,结合作者以往研究结果认为病窦者并非单一电生理机制的实体。SAE 为这一研究提供了新的途径。
In this paper, 104 patients were divided into normal control, sinus lesion sinus Zheng three groups of electrophysiological studies. SACTi and SACTd measured by SAE and Strauss program stimuli were 92.8 ± 21.7 and 94.4 ± 16.5; 128.1 ± 60.3.130 ± 34.2 and 144.6 ± 48.6 and 146.1 ± 34.2 (ms), respectively. The mean of two groups in each group showed a linear correlation, with no significant difference between the two groups. SAE law that practical. SACTd is more accurate when program stimuli have a significant effect on SAN autonomy and conductivity. Because SACTi is influenced by many methodological factors, SACTd is closer to true value with sinoatrial normal and retrograde transmission. SACT and cSNRT anomaly detection rate and extension of the degree of Sick sinusitis group was significantly higher than the sinus slow group, combined with the authors previous studies suggest that sick sinus is not a single entity of the electrophysiological mechanism. SAE provides a new way for this research.
