Abstract:
A heart stimulator provides for a more appropriate yet simple setting of the AV-delay. The heart stimulator comprises a stimulation pulse generator adapted to generate electric stimulation pulses and connected to a ventricular stimulation electrode for delivering electric stimulation pulses. A sensing stage connected to an electrode for picking up electric potentials inside a ventricle is adapted to sense an excitation or a contraction of a heart chamber. A memory is adapted to store parameters defining a Bezier function determining the relationship between AV-delay values and heart rate and a control unit connected to said memory, said sensing stage and to said stimulation pulse generator, is adapted to determine an actual AV-delay based on an actual intrinsic heart rate or an actual stimulation rate and a non-linear smoothing interpolation between said parameters stored in said memory.
Abstract:
A heart stimulator for stimulating a chamber of a heart by way of electrical stimulation pulses, said pacemaker comprises a sensing stage connected or being connectable to an electrode lead comprising an electrode for picking up electric potentials inside a heart chamber, said sensing stage being adapted to sense an excitation of a heart chamber by way of picked up electric potentials, a stimulation pulse generator adapted to generate electric stimulation pulses and being connected or being connectable to an electrode lead comprising a stimulation electrode for delivering electric stimulation pulses to said chamber of a heart, and a control unit being connected to said sensing stage and to said stimulation pulse generator and being adapted to trigger stimulation pulses to be generated by the stimulation pulse generator and to be delivered via said electrode lead, said stimulation pulses being triggered with a controlled stimulation rate controlled by the control unit. For preventing too high a stimulation rate for too long a period of time a monitoring stage is provided that connected to the control unit and being adapted to monitor said controlled stimulation rate and override the controlled stimulation rate by a fixed stimulation rate for a predetermined period of time if the average controlled stimulation rate exceeds a predetermined maximum rate.
Abstract:
The present invention relates to an integrated outlet that allows supply of AC power to an outlet receptacle when certain conditions are satisfied. The integrated outlet contains separate modules to establish electrical connection with electrical conductors that transmit AC and DC power, telecommunications, control communications, and signals transmitted along a coaxial wire. In a preferred embodiment, these electrical conductors are disposed on two cables. Each module within the integrated outlet attaches to only certain standard conductors in each of the two cables. The integrated outlet can then be efficiently connected to the conductors in each of the two cables.
Abstract:
An implantable cardiac device includes a housing (2), pulse generator (7) therein to generate physiologically effective electrical pulses, a shock lead (3), externally of the housing (2), connectable to the pulse generator (7) and implantable into a patient's body to apply physiologically effective electrical pulses to the patient's body, a monitor (8) to automatically detect a lead condition as to whether the shock lead (3) is implanted or not, and control (9), which due to the detected lead condition automatically enables or disables the pulse generator (7).

Abstract:
A heart stimulator for electrical stimulation of a heart chamber includes a sensing stage sensing excitation of the heart chamber via an electrode lead having an electrode for picking up heart chamber electric potentials, a stimulation pulse generator generating electric stimulation pulses for delivery to the heart chamber via a stimulation electrode, and a control unit connected to the sensing stage and the stimulation pulse generator and being adapted to trigger the stimulation pulses at a controlled stimulation rate. A monitoring stage is provided for preventing too high of a stimulation rate for too long of a period of time, with the monitoring stage being connected to the control unit and being adapted to monitor the controlled stimulation rate, and to override the controlled stimulation rate by a fixed stimulation rate for a predetermined period of time if the average controlled stimulation rate exceeds a predetermined maximum rate.

The integrated outlet contains separate modules establish electrical connection with electrical conductors that transmit AC and DC power, telecommunications, control communications, and signals transmitted along a coaxial wire. In a preferred embodiment, these electrical conductors are all disposed on a single ribbon cable. Each module within the integrated outlet can attach to only certain conductors to increase safety in the resulting system.
