A device for verifying the differentiation of tachycardia events in medical devices with dual sensing vectors

摘要

A method and medical device for detecting a cardiac event, the method comprising sensing a cardiac signal from a plurality of electrodes forming a first sensing vector sensing a first interval and a second sensing vector sensing a second interval. Determining, for each of the first and second intervals, whether each beat of the plurality of beats is one of a matching beat and a mismatching beat; and Determining whether the pulse is one of a high-reliability beat and a low-reliability beat, and each of the first interval and the second interval is determined to be a discordant beat and a high-reliability beat. Delivering therapy in response to determining that the number of beats that are present is greater than a threshold and identifying each of the first and second intervals as being shockable or not shockable Determining whether or not to Legal and medical devices.
