Patent number: 10368808Abstract: Embodiments describe a method of determining etiology of undiagnosed events comprising monitoring electrocardiogram signals and blood pressure of a patient via a medical device, capturing one or more of an ECG segment and a BP reading in response to a triggering event, classifying one or more of the ECG segment and BP reading as normal or abnormal, and determining etiology of undiagnosed symptomatic events based on the classification. Embodiments further describe a medical device comprising sensors for monitoring ECG signals and BP of a patient, circuitry for capturing one or more of ECG segments and BP readings of a patient in response to a triggering event, and a processor for communicating one of more of captured ECG segments and captured BP readings to a remote monitoring center directly or indirectly where the captured ECG segments and captured BP readings are classified as normal or abnormal.Type: GrantFiled: November 2, 2016Date of Patent: August 6, 2019Assignee: Medtronic Monitoring, Inc.Inventors: Brian B.

Patent number: 10342445Abstract: A system and method of monitoring electrocardiogram (ECG) signals and detecting ischemic conditions. In particular, high-frequency components and low-frequency components are extracted from the monitored ECG signal. The high-frequency components are analyzed to detect reduced amplitude zones (RAZs), while the low-frequency components are utilized to detect premature ventricular contraction (PVC) beats. Potentially ischemic conditions are identified based on both RAZs and PVC beats detected.Type: GrantFiled: November 3, 2016Date of Patent: July 9, 2019Assignee: Medtronic Monitoring, Inc.Inventors: ShaileshKumar V. Musley, Maneesh Shrivastav, Stacie Vilendrer

Patent number: 8372013Abstract: A method of determining a respiration parameter in a medical device in which pressure signals are sensed to generate corresponding sample points, and a breath detection threshold is continuously adjusted in response to the generated sample points to generate a current adjusted breath detection threshold. A current generated sample point is compared to the current adjusted breath detection threshold, and the continuous adjusting of the breath detection threshold is suspended and the breath detection threshold is equal to the most current adjusted breath detection threshold generated prior to the suspending in response to the comparing. A next sample point, generated subsequent to the suspending, is compared to the set breath detection threshold, and the respiration parameter is determined in response to the comparing of a next sample point to the set breath detection threshold.Type: GrantFiled: October 31, 2008Date of Patent: February 12, 2013Assignee: Medtronic, Inc.Inventors: Maneesh Shrivastav, Yong K.

Patent number: 7831304Abstract: An implantable medical device system and method detect oversensing of cardiac signals. A cardiac signal including first events and second events is acquired. Cardiac events are sensed in response to the cardiac signal crossing a first threshold. A filtered cardiac signal is determined from the sensed cardiac signal, and a second threshold is determined from the filtered cardiac signal. A sensed cardiac event is classified either as a first event when the sensed cardiac event corresponds to a filtered cardiac signal peak crossing the second threshold or a second event when the sensed cardiac event corresponds to a filtered cardiac signal peak being less than the second threshold. Classification of sensed cardiac events as second events is used in determining oversensing.Type: GrantFiled: September 29, 2006Date of Patent: November 9, 2010Assignee: Medtronic, Inc.Inventors: Jian Cao, Jeffrey M.
