    摘要: An external defibrillator includes patient electrodes (20) for obtaining the patient's electrocardiogram (ECG) and for applying a shock to the patient. A microprocessor (24) analyses the patient's ECG using a diagnostic algorithm to detect if the patient's heart is in a shockable rhythm, and shock delivery circuitry (10) is enabled when a shockable rhythm is detected by the diagnostic algorithm. The patient electrodes also allow obtaining a signal (Z) which is a measure of the patient's transthoracic impedance and the microprocessor is responsive to Z to detect conditions likely to cause the diagnostic algorithm to generate a false detection of a shockable rhythm. If such detection is made, the microprocessor prevents detection of a shockable rhythm by the diagnostic algorithm, at least for a period of time.

    摘要: An implantable cardiac stimulation device (10) contains a high voltage defibrillating unit (16). A protection circuit (60) is connected to the defibrillating unit to guard against excessive current during a high voltage discharge. The protection circuit prevents damage to the defibrillation unit and to the associated heart tissue (12). The defibrillation current is monitored by the protection circuit and, if excessive, the defibrillation current is reduced by routing the current through an additional impedance. The protection circuit operates in real time to remove the additional impedance if the defibrillation current returns to a safe level. A memory device attached to the protection circuit records the event of an excessive defibrillation current.

    摘要: The invention relates to a defibrillator comprising an output stage that has a high-voltage section (1, 2) and patient electrode connections (PEA), which can be automatically connected by a coupling circuit (3) to said high-voltage section via a relay (3.1), and has a relay testing device. A reliable functioning of the defibrillator is ensured due to the provision of a discharging resistor device (RD), which can be automatically switched to instead of the patient electrode connections (PEA) by means of the relay (3.1), and by virtue of the fact that the relay testing device is designed for testing the relay (3.1) while involving the state of the adjacent discharging resistor device (RD).

    摘要: The invention has an object of providing a disarm circuit using a semiconductor switch device that can secure the safety of an electrotherapy apparatus by disarming even if the control of the semiconductor switch is disabled because of some cause. Therefore, the disarm circuit is provided with a transformer, its primary side area, its secondary side area, a resistor for disarming and the semiconductor switch device. The secondary side area is characterized in that a resistor for limiting excessive current for automatically turning on the semiconductor switch device by stored electric energy is connected between a positive terminal of an electric energy storage section and the gate of the semiconductor switch device.
