摘要： The invention relates to ventricular tachyarrhythmia detection and classification. Upon detection of a ventricular tachyarrhythmia based on an electrocardiogram signal, cardiogenic impedance data representative of ventricular volume dynamics are collected and used for classifying the detected tachyarrhythmia as stable or unstable. In the latter case but typically not in the former case, defibrillation shocks or other forms of therapy are applied to combat the unstable ventricular tachyarrhythmia.

摘要： The present invention relates generally to methods and systems for optimizing stimulation of a heart of a patient. More specifically, hemodynamical index signals reflecting a mechanical functioning of a heart of a patient are recorded at different hemodynamical states. Further, corresponding hemodynamical reference signals at corresponding hemodynamical states are recorded. Further, at least one hemodynamical index parameter is extracted from the recorded hemodynamical index signals, the at least one hemodynamical index parameter being a measure of the mechanical functioning of the heart and a hemodynamical index model is created, wherein the hemodynamical index model is based on the at least one hemodynamical index parameter and a comparison between output results from the hemodynamical index model and corresponding hemodynamical reference signals. From this hemodynamical index model, a hemodynamical index can be derived, which then can be used in determining patient customized cardiac pacing settings of the cardiac stimulator.

摘要： The invention concerns an implantable heart monitoring device (10) comprising, inter alia, a control circuit (14) configured to be able to measure an impedance across at least part of an atrium, such that the variation of the impedance is related to the volume change of the atrium. The control circuit (14) is configured to carry out certain steps, and to store values at different occasions that indicate the rate of change of the meas¬ ured impedance. The stored values have been determined such that, when the device (10) is used in a living being, the variation of the stored values will be related to the variation of the speed with which the atrium is filled with blood during the atrial dias¬ tole. The invention also concerns a corresponding system and method.

摘要： An implantable medical device (100) is connectable to an epicardial multi-electrode lead (200) employed for registering a depolarization wave propagation pattern across a ventricle (12) of a heart (10).
