pacing threshold

The deeper were the coronary sinus leads, the lower the pacing threshold.

冠状静脉窦电极位置较深, 则测得起搏阈值较低.

Pacing threshold was 0.6±0.2 V. Pacing impedance was 540.0±110.8 ohms.

起搏阈值0.6±0.2V.起搏阻抗540.0±110.8Ω.

The Effects of Diltiazem Hydrochloride on Permanent Heart Pacing Threshold and Intracordial Electrical Signal Amplitude

盐酸地尔硫卓对永久人工心脏起搏器起搏阈值及心内电信号波幅的影响

There were no statistical significant in the pacing threshold, sensitivity and lead impedance in two groups ( all P> 0.05).

两组起搏电压、感知、阻抗差异无显著性（P值均>0.05）。

Objective: To observe the effects of propafenone hydrochloride injection on permanent heart pacing threshold and endocardial electrical signal amplitude.

目的：探讨静脉注射盐酸普罗帕酮注射液对永久人工心脏起搏器心房、心室起搏阈值及心内电信号P波、R波振幅的影响。
