The present invention relates to a universal adaptor that allows one to connect electrodes and/or electrode pads from a patient that is experiencing heart problems to an EKG and/or defibrillator from a different manufacturer from the manufacturer of the electrodes and/or electrode pads. The invention also relates to methods of saving a patient's life by eliminating the process and time that it would take to transfer electrodes and/or electrode pads on a patient by using this universal adaptor.

A wearable cardioverter defibrillator system includes a support structure that a patient can wear. The system also includes electrodes that contact the patient, and define two or more channels from which ECG signals are sensed. A processor may evaluate the channels by analyzing their respective ECG signals, to determine which contains less noise than the other(s). The analysis can be by extracting statistics from the ECG signals, optionally after first processing them, and then by comparing these statistics. These statistics may include tall peak counts, amplitudes of peaks compared to historical peak amplitudes, signal baseline shift, dwell time near a baseline, narrow peak counts, zero crossings counts, determined heart rates, and so on. Once the less noisy signal is identified, its channel can be followed preferentially or to the exclusion of other channels, for continuing monitoring and/or determining whether to shock the patient.

A monitor that includes multiple detection channels having multiple input ports for receiving a group of electrical physiological signals from a person; wherein multiple switching circuits of the monitor are configured according to a first configuration when the monitor operates in a first mode, thereby causing each electrical physiological signal of the group to be processed by up to a single selected detection channel of the multiple detection channels; wherein the multiple switching circuits of the monitor are configured according to a second configuration when the monitor operates in a second mode thereby causing one or more of the multiple electrical physiological signals of the group to be processed by at least two selected detection channels of the multiple detection channels.

A wearable ECG system includes a plurality of electrodes; a multiplexor, the multiplexor including an input port, two output ports, and a control port, the input port of the multiplexor being connected with the electrodes; an analog detection module being connected with one output port of the multiplexor; a digital detection module being connected with the other output port of the multiplexor; a processor being connected with the control port of the multiplexor and the digital detection module; and a motion detection module connected with the processor and configured to detect acceleration of the wearable ECG system and output an electrical signal accordingly. The processor is configured to receive the electrical signal from the motion detection module, and control the multiplexor to selectively transmit output of the electrodes to the analog detection module or the digital detection module based on the electrical signal.

An ECG sensor chip used in a wearable appliance includes; a switch controlled by a switching signal, an amplifier that amplifies a difference between first and second ECG signals, and a location indicator that generates the switching signal. The switch passes either a first ECG signal or second ECG signal in response to the switching signal.

Detecting user contact with one or more electrodes of a physiological signal sensor can be used to ensure physiological signals measured by the physiological signal sensor meet waveform characteristics (e.g., of a clinically accurate physiological signal). In some examples, a mobile and/or wearable device can comprise sensing circuitry, stimulation circuitry, and processing circuitry. The stimulation circuit can drive one or more stimulation signals on one or more electrodes, the resulting signal(s) can be measured (e.g., by the sensing circuitry), and the processing circuitry can determine whether a user is in contact with the electrode(s). Additionally or alternatively, in some examples, mobile and/or wearable device can comprise saturation detection circuitry, and the processing circuitry can determine whether the sensing circuitry is saturated.
