1. A cardiac monitoring device comprising a wearable unit comprising:

  • a substrate;

    a measuring arrangement for measuring ECG signals;

    a data processing arrangement comprising a data processor; and

    a wireless transmitter;

    wherein the data processing arrangement is sealed within the substrate and arranged to receive the measured ECG signals, to obtain sampled signal data by sampling each ECG signal associated with a heartbeat, to process the sampled signal data in the data processor to extract key data relating to that heartbeat, and to provide the key data to the wireless transmitter for transmission; and

    wherein the data processor is programmed to apply a time window to the sampled signal data to isolate at least a portion of the data associated with a given heartbeat and measure amplitude changes in that window, the amplitude changes being used to identify key data comprising a temporal position of a characteristic feature in the ECG signal and at least one further time or amplitude value corresponding to one or more pre-defined features of the ECG signal.
