用于在医疗设备中辨别心动过速事件的方法和装置
摘要：
用于检测心脏事件的方法和医疗设备，包括感测来自多个电极的心脏信号，所述多个电极形成第一感测向量和第二感测向量；响应于对在预定的感测窗期间沿着所述第一感测向量感测的第一间期和沿着所述第二感测向量同时感测的第二间期的第一处理，将所述心脏事件标识为可电击事件和不可电击事件之一；响应于将所述心脏事件标识为可电击事件，执行对所述第一间期和所述第二间期的不同于所述第一处理的第二处理；以及响应于对所述第一间期和所述第二间期的第二处理，判定是否延迟将所述心脏事件标识为可电击的。
摘要（英）：

A method and medical device for detecting a cardiac event that includes determining, in response to the cardiac event being identified as a shockable event, a first R-wave morphology corresponding to R-waves of a next interval subsequently sensed along a first sensing vector and a second R-wave morphology corresponding to R-waves of a next interval subsequently sensed along a second sensing vector, determining whether the next interval subsequently sensed along the first sensing vector and the next interval subsequently sensed along the second sensing vector satisfy a morphology metric, and identifying the cardiac event as one of a monomorphic ventricular tachycardia and a polymorphic ventricular tachycardia in response to the determined first R-wave morphology, second R-wave morphology, and the next interval subsequently sensed along the first sensing vector and the next interval subsequently sensed along the second sensing vector not satisfying the morphology metric.
