Health Monitoring
First Claim
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.

Abstract
Health monitoring devices allow for monitoring of the vital signs of a subject. Wireless devices can enable a subject'"'"'s cardiac and/or respiratory functions to be monitored remotely, e.g. without the subject being attached to bedside equipment. A cardiac monitoring device may include a substrate, electrodes for measuring ECG signals, and an electronics module including a data processor and a wireless transmitter. The electronics module is sealed within the substrate and arranged to receive the measured ECG signals. Each ECG signal associated with a heartbeat is processed in the data processor to provide key data relating to that heartbeat. The key data may include the temporal position of a characteristic feature in the ECG signal. The key data is provided to the wireless transmitter for transmission.
