摘要： A medical device is configured to sense an electrical signal and determine that signal to noise criteria are met based on electrical signal segments stored in response to sensed electrophysiological events. The medical device is configured to determine an increased gain signal segment from one of the stored electrical signal segments in response to determining that the signal to noise criteria are met. The medical device determines a noise metric from the increased gain signal segment. The stored electrical signal segment associated with the increased gain signal segment may be classified as a noise segment in response to the noise metric meeting noise detection criteria.

摘要： An implantable medical device system is configured to detect a tachyarrhythmia from a cardiac electrical signal and start an ATP therapy delay period. The implantable medical device determines whether the cardiac electrical signal received during the ATP therapy delay period satisfies ATP delivery criteria. A therapy delivery module is controlled to cancel the delayed ATP therapy if the ATP delivery criteria are not met and deliver the delayed ATP therapy if the ATP delivery criteria are met.

摘要： A medical device, such as an extra-cardiovascular implantable cardioverter defibrillator, is configured to store a cardiac signal segment in response to sensing a cardiac event and obtain a notch filtered signal segment by notch filtering the cardiac signal segment. The medical device determines a count of crossings of the notch filtered signal segment by the cardiac signal segment and determines whether electromagnetic interference (EMI) is present in the cardiac signal segment based on a value of the count.

摘要： An extra-cardiovascular implantable cardioverter defibrillator senses R-waves from a first cardiac electrical signal by a first sensing channel and stores a time segment of a second cardiac electrical signal in response to each sensed R-wave. The ICD determines intervals between successively sensed R-waves and, in response to at least a predetermined number of the intervals being less than a tachyarrhythmia detection interval, analyzes at least a portion of the time segment of the second cardiac electrical signal corresponding to a most recent one of the sensed R-waves to confirm the most recent one of the R-waves. The ICD updates an unconfirmed beat count in response to the most recent one of the R-waves not being confirmed and withholds detection of a tachyarrhythmia episode in response to the unconfirmed beat count being equal to or greater than a rejection threshold.

摘要： An implantable medical device system includes an implantable cardioverter defibrillator (ICD) for detecting and treating ventricular tachycardia (VT). The ICD includes a sensing module for sensing a cardiac signal from selected cardiac signal sensing vectors. A control module generates morphology templates of the cardiac signals for multiple patient postures for each of the available sensing vectors. A cardiac signal received during an unknown cardiac rhythm is compared to the morphology templates without determining a current posture of the patient. The unknown cardiac rhythm is detected and classified as supraventricular tachycardia in response to the cardiac signal matching at least one of the morphology templates.
