基础心率

结论：感知电流、起搏电压和阈值是影响单腔PM寿命最重要的因素，患者基础心率、电池容量、起搏频率、阻抗和脉宽对单腔PM使用寿命也有不同程度的影响。

Conclusion : Sensing current , pacing electric voltage and threshold value are the most important affecting of factor PMs ′ longevity , and patients ′ basal heart rate , battery capacity , pacing frequency , electric resistance and pulse width also influence the longevity in different digrees .

单因素统计分析显示：患者基础心率、电池容量、起搏电压、起搏频率、阻抗、阈值、脉宽和感知电流对PM的寿命均有影响（均P<0.05）。

Patient ′ s basal heart rate , battery capacity , pacing electric voltage , pacing frequency , resistance , threshold value , pulse width and sensing electric current had all affected the PM ′ s longevity ( all P < 0.05 ) counted by Wilcoxon ( Gehan ) test .
