In a particular embodiment, a method of displaying an electrocardiogram rhythm can include receiving an electrocardiogram signal and applying an algorithm to the signal to determine a rhythm diagnosis or recommended therapy. The method can further include displaying a color and/or a pattern corresponding to the rhythm diagnosis or recommended therapy. In various embodiments, the method can be performed in real time or on a pre-recorded signal for post-event analysis.Type: ApplicationFiled: September 4, 2013Publication date: March 6, 2014Inventors: Lawrence D. Sherman, Elijah D. Christensen, Mickey Eisenberg, Peter J. Kudenchuk, Christopher Neils, Thomas Rea

Patent number: 8660640Abstract: An volume of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of a volume can be determined based upon the sensing of the plurality of points without the use of other imaging devices. An implantable medical device can then be navigated relative to the mapping data.Type: GrantFiled: April 14, 2009Date of Patent: February 25, 2014Assignee: Medtronic, Inc.Inventors: H.

Publication number: 20140051942Abstract: A data collection module receives signals generated using at least one of an electromyography (EMG) sensor connected to a user, an electroencephalography (EEG) sensor connected to the user, an electrocardiogram (ECG) sensor connected to the user, and an oxygen saturation (SPO2) sensor connected to the user. A mobile computing device is implemented independently of the data collection module and communicates with the data collection module. The mobile computing device includes a processor and a tangible computer readable medium including a sleep study application embodied as code for: selectively prompting the data collection module to store data samples generated based on the signals; receiving the data samples from the data collection module; and transmitting sleep study data including the data samples to a first data server. The mobile computing device further includes a communications module that wirelessly downloads the sleep study application from a second data server.Type: ApplicationFiled: February 27, 2013Publication date: February 20, 2014Applicant: GOOD SLEEP, LLCInventor: Christopher J.

Patent number: 8655434Abstract: A physician's programmer for an implantable device is disclosed. The programmer includes a receiver for receiving wireless transmission data from the implantable heart monitor. A processor is configured to extract from the wireless transmission data ST-deviation histogram data as a function of heart rate. The histogram data for a particular heart rate range is shown on a display in the form of a bar chart. The histogram data for a plurality of heart rate ranges is shown in the form of a chart with multiple line plots.Type: GrantFiled: May 1, 2012Date of Patent: February 18, 2014Assignee: Angel Medical Systems, Inc.Inventors: David R. Fischell, Robert E. Fischell, Jonathan Harwood, Steven R. Johnson

Patent number: 8649854Abstract: The present invention is related to a method for the determination of frequency band characteristics of a heart disease. A first set of phonocardiograms are recorded from a first set of reference healthy patients, and a second set of phonocardiograms from a second set of patients suffering of a heart disease. Spectral energies of all possible frequency bands are then calculated. These spectral energies are then compared in order to determine an optimized frequency band that gives rise to the maximal distinction between spectral energies of the phonocardiograms from first and second set of phonocardiograms.Type: GrantFiled: February 6, 2009Date of Patent: February 11, 2014Assignee: Capis SPRLInventors: Amir A.

Publication number: 20140039338Abstract: Measured values of ST segment deviations obtained from a multi-lead ECG are transformed and displayed on a polar ST Circle Display, with zero ST deviation values located on a circle having a diameter that is greater than a maximum absolute ST segment deviation value obtained for any measured or derived lead. An ischemic condition and a location of the ischemia can thereby be easily determined.Type: ApplicationFiled: October 9, 2013Publication date: February 6, 2014Applicant: Draeger Medical Systems, Inc.Inventors: Stefan Nelwan, Wolfgang Scholz
