摘　　要：目的研究心律失常联律间期改变对血液动力学的影响。方法经心电图检查证实为心律失常患者179例,正常窦性心律30例,经食道心房调搏检查人工模拟房性早搏90例次,再应用心功能仪及信号处理技术对上述检查者的桡动脉图形进行面积积分。结果早搏提前率相同情况下:桡动脉图积分面积在提前率>40%时最小,20%～40%时居中,<20%时最大,(P<0.05);自发、人工房早桡动脉图积分面积两组间差异无显著性(P>0.05)。窦性心律不齐桡动脉图积分面积:最短P-P间期组最小,居中P-P间期组居中,最长P-P间期组最大,(P<0.05)。房颤桡动脉图积分面积:R-R间期<600ms组最小,R-R间期600～1000ms组居中,R-R间期>1000ms组最大,(P<0.05);3组与窦性心律组比较均差异有显著性(P<0.05)。结论心律失常对血液动力学的影响与联律间期长短密切相关。[Objective] To study the effect of coupling intervals change of arrhythmia on the hemodynamies. [Methods] 179 patients with arrhythmia, 30 healthy controls and 90 examples with artrial premature beat who were induced through the technique of transesophageal artrial pacing test were detected by twelve-lead surface electrocardiograms. Above-mentioned examiners were investigated through cardiac function check apparatus. The pulsographic areas were measured by signal processing technique. [Results] The pulsographic areas of premature beat were smallest when advanced ratios were 〉40%, middle when the ratios were between 20%-40%, and largest when the ratios were 〈20% （P 〈0.05）; there were no correlations between spontaneous and artificial artrial premature beat （P 〉0.05）. The pulsographic areas of respiratory sinus arrhythmia was positive correlation when the P-P intervals were the shortest, middle and longest. The pulsographic areas of Af were smallest at the R-R intervals 〈600 ms. Which were middle at the R-R intervals between 600-1000 ms, and largest maximum at the R-R intervals 〉1000 ms. They were significantly different （P 〈0.05）. [Conclusions] There is a positive correlation of the coupling interval of arrhythmia with hemodynamies.
