摘要： In a method for increasing the energy output from a number of charged capacitors each of the capacitors is discharged, one after another, through a load. The capacitors are then coupled in series in successive, different combination, each of which includes a part or all of the capacitors. These combinations are and being discharged, one after another, through the load. An apparatus for increasing the energy output from a number of charged capacitors includes comprises a charging circuit, arranged to control the charging of the capacitors, and a controllable switching device, arranged to first connect each of the capacitors to a load for discharge of the capacitors, on after another. The switching device then couples the capacitors in series in successive, different combinations, each of which includes a part or all of the capacitors, and connects the respective combinations to the load for discharge of the series couplings, on after another.

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： In an implantable heart monitoring device and a monitoring method, an impedance is measured across at least part of an atrium, such that variation of the impedance is related to the volume change of the atrium. Values are stored at different occasions that indicate the rate of change of the measured impedance. The stored values are determined such that, when the device 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 diastole.

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： An implantable medical device that is physically connectable to the body of a user has an information manager that manages sensitive information associated with the user or the device. A sensor is connected to the device that senses whether the device is physically connected to the body of the user, and generates a signal indicating whether the device is actually connected to the body of the user. The information manager is connected to the sensor, and is responsive to the sensor signal so as to perform information managing functions based on the signal. Among other things, fraudulent retrieval of sensitive data from the device is prevented if the device is not connected to or implanted in the body of the user.

摘要： An implantable medical apparatus for detecting diastolic heart failure, DHF, has a DHF determining device for determining at least one blood pressure parameter for detecting a DHF state of the heart of a patient. The DHF determining device includes a pressure measuring unit for measuring pulse pressure in a cardiac cycle for a predetermined workload situation of the patient as the blood pressure parameter, and a comparator compares the measured pulse pressure with a predetermined reference value. A pacemaker includes such an apparatus and a control unit that optimizes pacing therapy depending on the result of the comparison of the measured pulse pressures with the predetermined reference values. A corresponding method of detecting diastolic heart failure, DHF, includes the step of determining at least one blood pressure parameter for detecting a DHF state of the heart of a patient by determining, as said blood pressure parameter, the pulse pressure in a cardiac cycle for a predetermined workload situation of the patient, and the determined pulse pressure is compared with a predetermined reference value.

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.
