  • Patent number: 4527567
    Abstract: An extra-corporeal, self-contained, on-line, beat-to-beat pacemaker function analyzer (PFA) for automatic evaluation and indication of the quality of performance of cardiac pacing systems implanted in place for: routine examination of ambulatory patients; long-term surveillance of hospitalized patients; and examination of ECG traces (including pacing artefacts) of remote pacemaker patients, transferred by telephone or radio to a central follow-up station. The PFA provides a comprehensive examination of asynchronous, demand and demand-hysteresis pacemakers of all makes, including the state of the pacemaker's battery, the intactness of the electronic circuitry and of the electrodes, and the proper location of the electrodes in the heart.

  • Patent number: 4445512
    Abstract: A pacemaker of the inhibited demand type which is equipped with a battery and pacemaker efficiency evaluator. A magnetically initialized test circuit synchronizes the timing of test stimulating pulses with the natural R-wave or, the end of a basic pacemaker escape interval, thereby to enhance patient safety by avoiding competition during testing. The synchronized test circuit produces an alternating sequence of sensing and pacing periods which are maintained during the test. Upon actuation of the test, the first R-wave, or the end of the basic pacer interval, is sensed and a number of stimulating pulses is applied at the end of successive test intervals, which intervals are located between pacemaker output pulses, the duration of which indicates the battery status. This sequence of sensing, synchronization, an application of test pulses is repeated during the duration of the magnet test.

  • Patent number: 4413224
    Abstract: A micropower DC/DC conversion system providing a stabilized voltage output at a predetermined voltage higher than that of the energy source. The system is powered by one or more primary cells in parallel or by a suitable battery, and the system is of special use with systems requiring low power at stabilized voltage which is substantially independent of the energy source impedance and load variations.According to the preferred embodiment of the system the output voltage stabilization is controlled by voltage detection circuit based on C-MOS inverters which allows extremely low power drain. The system is of special value for use with electronic implantable devices such as cardiac pacemakers.

  • Patent number: 4027663
    Abstract: A heart beat detector for use in emergencies and especially under adverse conditions of noise and vibration, of the type adapted to continuously monitor the ECG, extracting the QRS complexes and signalling the occurrence of heart beats by easily perceptible, light signals. The detector includes an inter-electrode impedance sensor; for automatically ascertaining whether adequate conductivity exists between the body of the patient and the electrodes of the detector applied to said body. According to a specific embodiment of the invention the device comprises a sub-system adapted to indicate the activity of the batteries of the instrument, the state of the electrodes and of the other circuits.
