摘要
目的 通过对起搏多参数分析以寻找最佳起搏位置 ,把病人的痛苦程度降到最小。方法 90 7例经食管心房调搏 (TEAP)的病人 ,分析身高、插管深度、食管导联P波振幅及方向和起搏阈值 ,对统计数值行相关分析。结果 食管电极导管插入的深度与病人的身高有显著的相关性 (P <0 .0 0 1) ;食管导联P波振幅的高低与起搏阈值呈负相关 (P <0 .0 0 1) ;3种不同P波形态与起搏阈值组间无差异 (P >0 .0 5 )。结论 病人的身高可预测插管的深度 ;食管导联P波振幅越大 ,所用起搏阈值则越小 。
Objective To get the optimal pacing site through analysis of parameters to decrease patients' discomfort.Method The patient's height,length of inserted catheter,amplitude and direction of P wave at esophagus lead and pacing threshold were studied with SPSS software on 907 patients with transesophageal atrium pacing.Results The patient's height and the length of catheter to be inserted are closely related.The amplitude of P wave and pacing threshold show negative correlation.The pacing threshold is no difference in three groups of different direction of P wave (P>0.05).Conclusion The patient's height can be the parameter for the depth of catheter to be inserted.The amplitude is in inverse proportion to the pacing threshold,but has no relation with P wave direction.=
