摘要： Techniques for determining whether one or more leads are not adequately connected to a patient, e.g., for ECG monitoring, are described. The techniques involve injection of an integrated signal (which includes a test signal) into one lead, and monitoring the driven lead and the response at the other leads, including the common mode and the difference between the other leads. These “lead-off” detection techniques may be provided by an external defibrillator that provides three-wire ECG monitoring. Techniques for determining a type of a cable coupled to a defibrillator are also described. The cable-type identification may allow a defibrillator to, for example, operate in either a three-wire ECG monitoring mode or a therapy mode, based on whether a three-wire ECG cable or a defibrillation cable is coupled to the defibrillator.

摘要： Techniques for amplifying a plurality of input voltages to generate a corresponding plurality of output voltages. In an exemplary embodiment, each of the plurality of input voltages is referenced to a common voltage comprising the average of the plurality of input voltages, without the need to reference an independently provided common voltage. In an alternative exemplary embodiment, techniques are provided for automatically measuring the input impedance between any two nodes corresponding to the plurality of input voltages. Further techniques are provided for coupling input nodes of the amplifier modules to a common reference voltage, and to the housing of the apparatus.

摘要： The invention presents techniques for identifying signals detected by electrodes on the body of a patient as part of a reading of the patient's electrocardiogram. A signal processor digitally filters the signal from the body, resulting in an electrocardiogram signal and a signal that identifies the presence and timing of signals from a pacemaker in the body. Other signals, such as a signal that reflects the quality of the electrical connection of the electrode to the body, may also be obtained by digital filtering.
