DEVICE FOR DETECTING OVERSENSING OF CARDIAC

A medical device configured to detect an alternating pattern of signal characteristics determined from successive segments of a cardiac electrical signal and determine an overall morphological metric from at least one segment of the cardiac electrical signal. The device is configured to detect cardi...

Zusammenfassung:A medical device configured to detect an alternating pattern of signal characteristics determined from successive segments of a cardiac electrical signal and determine an overall morphological metric from at least one segment of the cardiac electrical signal. The device is configured to detect cardiac event overinduction in response to detecting the alternating pattern and an overall morphological metric that does not meet tachyarrhythmia morphological criteria. The medical device may refrain from detecting an arrhythmia in response to detecting that the cardiac event is overinduced. 一种医疗设备,该医疗设备被配置为检测从心脏电信号的连续分段确定的信号特征的交替模式,并从该心脏电信号的至少一个分段确定总体形态度量。该设备被配置为响应于检测到该交替模式和不满足快速性心律失常形态标准的总体形态度量来检测心脏事件过度感应。该医疗设备可响应于检测到该心脏事件过度感应而制止检测心律失常。
