A new software architecture for automatic interpretation of the electrocardiogram is presented. Using the hypothesize-and-test paradigm, a semi-quantitative physiological model and production rule-based knowledge are combined to reason about time- and space-varying characteristics of complex heart rhythms. A prototype system implementing the methodology accepts a semi-quantitative description of the onset and morphology of the P waves and QRS complexes that are observed in the body-surface electrocardiogram. A beat-by-beat explanation of the origin and consequences of each wave is produced. The output is in the standard cardiology ladder diagram format. The current prototype can perform the full differential diagnosis of 2:1 atrioventricular (AV) block, and can handle correctly complex rhythms such as AV nodal reentrant tachycardia with either hidden or visible P waves, and varying degrees of AV block.
本文提出了一种用于自动解读心电图的新软件架构。使用假设-检验范式，将半定量生理模型和基于产生式规则的知识相结合，以推断复杂心律的时空变化特征。实现该方法的原型系统接受体表心电图中观察到的P波和QRS波群起始和形态的半定量描述。对每个波的起源和后果进行逐搏解释。输出采用标准心脏病学梯形图格式。当前的原型可以对2:1房室传导阻滞进行完整的鉴别诊断，并且能够正确处理复杂心律，如伴有隐匿或可见P波的房室结折返性心动过速以及不同程度的房室传导阻滞。
