摘要： The present invention relates generally to implantable medical devices and more particularly to systems and methods for stimulating a heart of a patient. A first ventricle is activated by delivering stimulation to at least one stimulation site, a point of time for arrival at the AV node for at least one depolarization wave resulting from the stimulation in the first ventricle is estimated and a first activation time interval substantially corresponding to the time interval required for at least one depolarization wave to travel from the stimulation site in the first ventricle to the AV node using the estimated point of time for arrival of the depolarization wave and a point of time for delivery of stimulation is computed. Thereafter, the other ventricle is stimulated by delivering stimulation to at least one stimulation site. A point of time for arrival at the AV node for at least one depolarization wave resulting from the stimulation in the other ventricle is then estimated and a second activation time interval substantially corresponding to the time required for at least one depolarization wave to travel from the stimulation site in the other ventricle to the AV node using the estimated arrival of the depolarization wave and the point of time for delivery of stimulation is computed. Based on these activation time intervals and a difference between the intervals, a pacing therapy can be determined, wherein the first ventricle is paced prior to activation of the other ventricle if the activation time difference indicates that the first activation time interval is longer than the second activation time interval and the other ventricle is paced prior to activation of the first ventricle if the activation time difference indicates that the second activation time interval is longer than the first activation time interval.

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： 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： 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). A signal processor (130) generates, based on the electrical activity sensed by the lead (200), a representation of the depolarization wave propagation pattern. A tachycardia classifier (140) of the medical device (100) classifies a tachycardia event of the heart (10) based on a comparison of the generated representation and a template representation of a template depolarization wave propagation pattern across the ventricle (12).

摘要： A biventricular stimulation device comprises a pulse generator for delivering stimulation pulses at least to the ventricles of a patient's heart. An evoked response detector has first and second, independent ventricular sensing channels for ventricular evoked response detection in the ventricles. The pulse generator is controlled to deliver stimulation pulses (106) to the second ventricle (RV) with a VV time delay after stimulation pulse delivery (104) to the first stimulated ventricle (LV) which is shorter than an evoked response detection time window (106) following the delivery of the stimulation pulse (104) to the first ventricle. The evoked response detector is arranged to close the evoked response detection time window (106) or discard detections therein in response to the emission of a stimulation pulse (107) to the second ventricle (RV) during the evoked response detection time window (106) of the first stimulated ventricle (LV).
