Conduction through the atrioventricular node (AVN) is assessed during electrophysiology study by relating the output to the input generated by an atrial extrastimulus. This extrastimulus scans electrical diastole of the heart to enable output to be plotted against input. Using this technique, we compared two mathematical models of the AVN, a rectangular hyperbola and a decaying exponential, respectively. The models were compared in 40 curves from 32 patients with only one AVN transmission pathway. Standard errors of the estimate were usually (25/40 trials) less with the exponential model, suggesting this the preferred algorithm for further development.
在电生理研究中，通过将房室结（AVN）的输出与心房额外刺激产生的输入相关联来评估其传导。这种额外刺激扫描心脏的电舒张期，以便能够将输出与输入进行绘图。使用该技术，我们比较了房室结的两种数学模型，分别是矩形双曲线模型和衰减指数模型。在32例仅有一条房室结传导通路的患者的40条曲线上对这些模型进行了比较。通常（25/40次试验）指数模型的估计标准误差较小，这表明它是进一步开发的首选算法。
