| 20100168812 | METHOD AND DEVICE FOR COLLECTING REM SLEEP DATA - In a method and a device for trending and prediction of monitored conditions or diseases, an REM sleep detector is provided to allow data collected during REM sleep to be separated from other data so stable and uniform conditions for data collection are achieved. The REM sleep detector can advantageously be provided inside an implantable medical device. | 07-01-2010 |
| 20100185252 | DEVICE AND METHOD OF A MEDICAL IMPLANT FOR MONITORING PROGRESSION OF HEART FAILURE IN A HUMAN HEART - In a device and method for a medical implant for monitoring progression of heart failure in a human heart, an activity sensor provides information related to the activity level of a patient and an oxygen sensor provides information related to the level of oxygen content in venous blood. A determined level of venous oxygen content at a determined activity level is obtained, and that level of venous oxygen content is compared to stored values at a corresponding activity level. The result of the comparison is used as a basis for determining a degree of heart failure. | 07-22-2010 |
| 20110106232 | METHOD AND DEVICE FOR ESTIMATING A MYOCARDIAL PERFORMANCE PARAMETER - An implantable medical device applies an electric signal to at least a portion of a heart in a subject. A resulting electric signal is collected from the heart and is used together with the applied signal for determining a cardiogenic impedance signal. The impedance signal is processed in order to estimate an isovolumetric contraction time, an isovolumetric relaxation time and an ejection time for a heart cycle. These three time parameters are employed for calculating a Tei-index of the heart. The Tei-index can be used as myocardial performance parameter in heart diagnosis and/or cardiac therapy adjustment. | 05-05-2011 |
| 20110112419 | IMPLANTABLE MEDICAL DEVICE AND METHOD FOR CLASSIFYING ARRHYTHMIA EVENTS - In an implantable medical device such as an implantable cardiac defibrillator, and a method for classifying arrhythmia events, IEGM signals are analyzed to detect an arrhythmia event and a respiratory pattern of the patient is sensed. At least one respiratory parameter reflecting characteristics of the respiratory pattern of the patient is determined based on the sensed respiratory pattern and a respiratory measure corresponding to a change of a rate of change of the at least one respiratory parameter is calculated. The detected arrhythmia event is classified based on the respiratory measure and the IEGM signals, wherein arrhythmia events that satisfy at least a first criterion is classified as an arrhythmia event requiring therapy. | 05-12-2011 |

| 20110160605 | IMPLANTABLE HEART MONITORING DEVICE AND METHOD - In an implantable heart monitoring device and method, particularly for monitoring diastolic dysfunction, a control circuit (a) detects the heart rate, (b) derives information correlated to the stroke volume of the heart at the detected heart rate, and (c) stores the detected heart rate and the derived information correlated to the stroke volume in a memory. The control circuit automatically implements (a), (b) and (c) at a number of different occasions for a number of different, naturally varying heart rates, so that the memory contains information indicating the stroke volume as a function of the heart rate. | 06-30-2011 |
