本文应用经食道心房调搏法测定72位病员的窦房结恢复时间(其中正常人32名,非病窦的心脏病者19名,病窦患者21名).结果表明病窦组与其他两组病人之间,窦房结恢复时间和校正窦房结恢复时间都有显著的差异(P<0.001)。窦房结恢复时间的正常高限为1,400毫秒,校正窦房结恢复时间的正常高限为500毫秒.两者超过正常高限,出现“第二抑制”现象和异位逸搏是病态窦房结综合征患者的特征性表现.实验表明经食道心房调搏法是一个安全、可靠而有效的非创伤性检查方法,值得推广.
In this paper, the recovery time of sinus node in 72 patients was determined by transesophageal atrial pacing method (32 normal subjects, 19 non-sick sinus patients and 21 sick sinus patients) There was a significant difference (P <0.001) between the group of patients, the time of sinus node recovery, and the time to correct sinus node recovery. The normal upper limit of sinus node recovery time was 1,400 milliseconds and the normal upper limit of the time to correct sinus node recovery was 500 milliseconds.They exceeded the normal high limit and appeared the phenomenon of “second inhibition” Results of syndromes in patients with characteristic manifestations.Experiments show that transesophageal atrial pacing method is a safe, reliable and effective non-invasive examination method, it is worth promoting.
