摘要： In a biventricular heart stimulator and a method for controlling such a biventricular heart stimulator, successive stimulation pulses are delivered to the ventricles of a heart such that stimulation pulses in a single heartbeat cycle are respectively first delivered to the first ventricle and then to the second ventricle. Capture or loss of capture in response to stimulation pulses delivered to one ventricle is detected. As a result of a detected loss of capture, preventative measures are taken for preventing loss of capture in the other ventricle.

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： A congestive heart failure monitor has an impedance measuring unit that measures the impedance between at least two electrodes implanted in a patient, to use a detected change of the measured impedance as an indication of a change in the left atrium volume. Any analyzing unit analyzes the measured impedance and detects insipient congestive heart failure dependent on a quotient of a maximum value of the measured impedance and a minimum value of the measured impedance during a cardiac cycle.

摘要： An implantable heart stimulating device has a left ventricular coronary sinus electrode lead provided with a tip electrode, a right ventricular electrode lead provided with a ring electrode, and a pulse generator connected to the leads that applies stimulation pulses between the tip electrode and the ring electrode, with the tip electrode serving as the anode. A monitoring unit monitors for and detects anodal capture at the right ventricular ring electrode subsequent to a stimulation. If anodal capture is detected, either a threshold search is performed by varying the pulse width and/or pulse amplitude of stimulation pulses in order to identify stimulation pulse characteristics that avoid anodal capture at the ring electrode, or at least one further electrode is activated to function as an indifferent electrode together with the ring electrode, also in order to avoid anodal capture at the ring electrode.

摘要： In an implantable heart stimulator and a method for operation thereof, stimulation pulses are delivered to a heart. The amplitude of the delivered stimulation pulses can be selectively set. For setting the amplitude, threshold searches are performed at selected time intervals. Each threshold search determines a threshold value required for achieving capture. The amplitudes of the respective stimulation pulses are set to a value that exceeds the determined threshold value by a safety margin. The safety margin is selected as a function of the selected time intervals.
