摘要： An atrium controlled heart pacemaker has a switching stage which is controlled in dependence upon the appearance of atrial signals. The switching stage switches the heart pacemaker to a VVI mode for a predetermined number of stimulation pulses or natural ventricular events, or a predetermined time, upon the appearance of at least one atrial signal before a selected time limit. The time limit is derived from the difference between a smallest synchronous interval and the AV delay.

摘要： An atrium-controlled heart pacemaker operates using set parameters including a smallest synchronous interval (SSI) between two stimulation pulses, a minimum atrial-ventricular delay time (AVmin) and a maximum atrial-ventricular delay time (AVmax). A control unit, dependent upon the appearance of an atrial signal, controls operation of the pacemaker such that the pacemaker operates with a variable pulse rate (DDD mode) when the atrial signal appears after a point in time SSI-AVmin, operates the pacemaker with a highest synchronous pulse rate when the atrial signal is between the points in time SSI-AVmin and SSI-AVmax, and causes no stimulation pulses to be emitted when the atrial signal appears before the point in time SSI-AVmax.

摘要： A cardiac pacer which generates pacing pulses at a predetermined pacing rate, includes a device for generating an alternating signal which is unable to pace the heart. The pacing pulses and the alternating signal are transmitted together to the heart. The alternating signal after transmittal to the heart is measured and processed such that a respiratory signal is obtained. The predetermined pacing rate is then varied dependent on the respiratory signal.

摘要： A circuit and method for detecting cardiac rhythm abnormalities employ unipolar signals respectively obtained from a cardiac lead having a tip at which a number of separate electrodes are disposed, the electrodes being simultaneously in contact with cardiac tissue. The respective unipolar signals which are obtained from the multiple electrodes exhibit a time relationship relative to each other, and this time relationship is analyzed to determine whether a cardiac rhythm abnormality is present or one or more of the unipolar signals is compared to a template which is known to represent a cardiac abnormality. Analysis of the time relation is undertaken by determining the absolute value of a time offset between any two of the unipolar signals, or by correlating any two of the unipolar signals.

摘要： An atrium-controlled heart pacemaker has a monitoring circuit for interrupting tachycardia which may be generated by the pacemaker. The monitoring circuit includes a P-wave counter and a window generator connected thereto. The window generator prescribes a window for the P-wave counter within which a predetermined maximum number n of P-waves is allowed to appear. When the n.sup.th P-wave appears in the window, forwarding of the n+1.sup.th P-wave to the stimulation circuit is blocked.

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： 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. 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 ischemia monitoring system has detectors for detecting the onset of an ischemic event of a tissue in subject, the end of the ischemic event and the end of a following recovery from the ischemic event, respectively. A time processor determines the duration of the ischemic event and the recovery period based on the detected onset and end times. A status processor co-processes the two determined time durations for the purpose of monitoring the ischemic status of the subject and detecting any deterioration in ischemic status for the latest ischemic event as compared to previous ischemic events that have occurred in the subject's tissue.
