摘要： A first ventricle is stimulated at a stimulation site, a point of time for arrival at the AV node for at least one depolarization wave resulting from the stimulation 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 is computed. A similar process is used to compute a second activation time interval for the other ventricle. Based on these activation time intervals and a difference between the intervals, a pacing therapy can be determined.

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： A pacemaker has control circuits contained in an enclosure and a lead containing an electrical conductor connected to an electrode for delivering electrical stimulation pulses to a heart. The stretching of a wall in the ventricle, corresponding to adequate filling of the ventricle in the heart, is determined in order to identify a time of emitting the stimulation pulses. This stretching is measured indirectly by measurement of pressure in the ventricle using a pressure sensor disposed near the lead in the ventricle. The signal from the sensor is supplied via the lead to circuitry in the enclosure, wherein the signal is amplified and is supplied to an edge detector, which detects an increasing or positive edge of the signal. The edge detector compares the incoming signal with a threshold value, and when the pressure indicated by the signal increases so as to exceed the threshold value, the edge detector supplies a signal to the control circuit which, in turn, triggers the emission of a stimulation pulse from a pulse generator, with or without a delay. The aforementioned stretching can also be measured using a strain gauge or a distance sensor attached to the ventricle wall.

摘要： An implantable bi-ventricular heart stimulating device (10) has a control circuit with first and second sensing circuits for respectively sensing in the two ventricles and first and second stimulation circuits for respectively stimulating the two ventricles. The control circuit determines whether a signal, sensed by said second sensing circuit, occurs essentially simultaneously with a signal sensed by the first sensing circuit. Furthermore, the control circuit determines whether a further signal is sensed by said second sensing circuit within a predetermined time interval which follows after the signal sensed by the second sensing circuit but within the same time cycle as that signal. If this occurs, the control circuit determines whether the sensed signals represent actual cardiac events, or are likely the result of far field detection.

摘要： In a system and method for monitoring cardiac synchrony in a human heart, a first sensor is positioned at a first cardiac wall location of a heart that is subject to movements related to longitudinal valve plane movements along the longitudinal axis of the heart, and the first sensor measures said cardiac wall movements at the first cardiac wall location and emits a first sensor output signal corresponding thereto, a second sensor is positioned at a second cardiac wall location of the heart that is subject to movements related to longitudinal valve plane movements along the longitudinal axis of the heart, and the second sensor measures the cardiac wall movements at the second cardiac wall location and emits a second sensor output signal corresponding thereto. A lead arrangement is electrically connected to the first and second sensors and conducts the first and second sensor output signals therefrom to processing circuitry that processes the first and second sensor output signals to produce a synchronization signal therefrom indicative of synchrony in the respective valve plane movements at the first and second cardiac wall locations.

摘要： In an implantable heart stimulating device, system and method, a control circuit has first and second circuits for sensing and pacing. The first circuit can be connected to a first electrode member suited to be positioned in or at a first ventricle of the heart. The second circuit can be connected to a second electrode member suited to be positioned in or at a second ventricle of the heart. The control circuit is able to detect whether signals sensed by the second circuit are likely to be far field signals. The control circuit performs this detection by at least determining whether, during a predetermined time (length, more signals are sensed by the second circuit than by the first circuit.

摘要： CRT settings for an implantable medical device are determined by applying pacing pulses to heart chambers of a scheme of different combinations of interchamber delays. A respective width parameter value representing an R or P wave width is determined for each such delay combination based on an ECG representing signal and the width parameter values are employed to estimate a parametric model defining the width parameter as a function of interchamber delays. Candidate interchamber delays that minimize the width parameter are determined from the parametric model and employed to determine optimal CRT settings. The technique provides an efficient way of finding optimal CRT settings when multiple pacing sites are available in a heart chamber.

摘要： In a method and implantable medical device for 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.
