我们采用经食道心房超速起搏对30例窦房结功能正常人及20例病态窦房结综合症病人测定了窦房结恢复时间(SRT)。方法起搏电极经鼻孔插入食道30～40厘米,起搏电压15～35伏,起搏时间为30秒、1分、2分,起搏频率为80、90、100、110、120次/分,在测得的数据中取其最大值作为SRT,并计算校正窦房结恢复时间(CSRT 及CSRT_2)。
We measured the time to sinus node recovery (SRT) in 30 patients with normal sinus node function and 20 patients with sick sinus syndrome using transesophageal atrial pacing. Methods Pacing electrodes were inserted into the esophagus 30 ~ 40 cm through the nostrils, the pacing voltage was 15 ~ 35V, the pacing time was 30 seconds, 1 minute and 2 minutes, the pacing frequency was 80, 90, 100, 110 and 120 times / , Take the maximum value in the measured data as the SRT, and calculate and correct the sinus node recovery time (CSRT and CSRT_2).
