摘    要:为了解起搏阈值、起搏阻抗和感知阈值的变化,对42根心房电极和49根心室电极进行了随访。结果显示:心房电极慢性期起搏阈值为1.17±0.35V/0.5ms,出现波动者6例(27.3%),心室电极为1.27±0.38V/0.5ms,出现波动者7例(30.4%);19根电极的起搏阻抗在急性期均有波动,慢性期为585.6±150Ω,慢性期出现波动者2例(10.5%);11根心房电极慢性期感知阈值(P波振幅)与植入时相一致。

关 键 词:起搏电极,起搏阈值,起搏阻抗,感知阈值

Abstract:Pacing thresholds were measured in 42 atrial leads and 49 ventricular leads follow-up.The results showed that chronic pacing threshold of atrial leads was 1.17±0.35 V/0.5 ms and chronic pacing threshold fluctuation occured in 6 patients(27.3%).Chronic pacing threshold of the ventricular leads was 1.27 ± 0.38 V/0.5ms and chronic pacing threshold fluctuation occured in 7 patients(30.4%).Pacing impedance were measured in 19 pacing leads follow-up.Chronic pacing impedance was 585.6±150 Ω.Acute pacing impedance fluctuaion occured in all of 19 leads,but chronic impedance fluctuaion occured in 2 leads(10.5%).Senstitivity threshold was measured in 11 patients with atrial leads follow-up and the result showed that chronic sensitivity threshold was consistent with P amplitude at implanting.
Keywords:Pacing lead Pacing threshold Pacing impedance Sensitivity threshold
