Wireless ECG recorder
Software for recording and analysis of electrocardiograms (ECG) using Pocket PC. It provides simultaneous recording of 12 leads and displaying up to 8 curves. It is possible to send ECG's to the hospital or evaluation center for analysis and receive confirmed interpretations using internet connection through mobile phone. Cardio CE is developed for Welch Allyn Cardio Control NV, Netherlands. The software is known as Cardio Perfect CE ®.

To integrate Bluetooth wireless terminal into the recorder, a small interface board for signal polarity and level alignment for UART and powering Bluetooth module was designed and implemented in the ECG recorder housing.
Heart Guard personal cardiomonitor
The basic idea of the project was to develop a user-friendly miniature wireless ECG recording and transmitting device (WERTD), and real-time ECG analysis and warning system (AWS), based on ordinary PCs or Pocket PCs for a patient's individual use.
Disturbances of heart function can be monitored and analysed with special software.
This new device is user friendly, it works at least 24 hours without the need to recharge batteries and allows patient to roam up to 30m from AWS (for example at home or hospital).
In the proposed system, the monitoring of three orthogonal Frank ECG leads is possible, as the conversion of these to conventional 12 ECG leads. It provides an opportunity for carrying out a more detailed analysis of ischemic changes in the heart as well as rhythm analysis.
Intelligent monitoring software contains ECG signal pre-processing, and events on ECG recognition and measurement parts. The recognised cardiac cycles will be analysed with two programmes. The first programme carries out the detection of conduction disturbances and ischemic ECG changes, which take place during various syndromes of coronary heart disease, such as stable angina pectoris, unstable angina pectoris and myocardial infarction. The second programme will be used for detection and analysis of rhythm disorders and unstable conduction disturbances.
