1. An apparatus comprising:

  • first and second electrodes configured and arranged to sense ECG signals from a subject; and

    an circuitry including;

    a digitizing circuit configured and arranged to receive and digitize the ECG signals sensed by the electrodes;

    an audio circuit including a microphone configured and arranged to capture voice sounds from the subject traveling through air, the audio circuit being configured and arranged to convert the captured voice sounds into electrical audio signals that can be reproduced for regenerating the voice sounds and therein providing audibly discernable speech;

    a processing circuit configured and arranged with the electrodes and digitizing circuit to digitize the ECG signals and to process each digitized ECG signal by at least one of;

    removing noise from the digitized ECG signal, storing the digitized ECG signal in a memory circuit, detecting a QRS complex in the digitized ECG signal, evaluating quality of the digitized ECG signal, and detecting arrhythmia in the digitized ECG signal;

    an input circuit configured and arranged to receive an input from the subject and including at least one manual switch configured and arranged to provide the input in response to the subject manually activating the at least one switch, the processing circuit and audio circuit being respectively configured and arranged with the input circuit to initiate recording of at least one of the ECG signals and the sound in response to the input; and

    a communication circuit configured and arranged to communicate the processed digitized ECG signals and the audio signals for receipt by an external device.
