With population on a steady increase it is intuitive to realize that an increase in people results in an increase of people needed medical attention which correlates to increased congestion in our hospitals.  This is why Wireless ECG Monitoring Systems (WEMS) has designed a wireless ECG monitoring device to allow for mobile monitoring through a designated area so that patients can be moved with ease to adapt to increasing space requirements.

The premise of this design is based around a Bluetooth wireless network which offers up to 5 ECG transmitters to connect to a single host station.  With an advanced security and error checking protocol Bluetooth is an ideal host for the wireless transmission of medical data.

From the patients end, the electrical action of the heart is captured using 4 electrodes with one for reference (ground), amplification and filtration follows, then the signal is processed in preparation for wireless transmission over a Bluetooth network.  At the receiving end, the signal is received from the Bluetooth network, filtered to remove any noise intrinsic to wireless transmission then displayed for medical staff to monitor. All data gathered is continuously logged into a database, and the time varying ECG signal is displayed in an intuitive graphical user interface at predetermined time intervals.  Each patient is assigned a reference ECG to which theirs will compared against so that in the event the patient’s heart signal changes, appropriate medical attention will be summoned.  The signals are compared using a unique Power Spectrum Density test. 


Further to this, the Wireless ECG Monitoring System features a robust reconnection algorithm so that if the patient becomes out of range from the receiving station, the device will automatically reconnect and continue to record data upon their return to the network.

Overall, much research has gone into the design and application of this device and advancements in biomedical engineering have enabled wireless medical monitoring to become a reality that is highly sought after by medical practitioners.
