Management of Non-uniform Data Transfer in Cardiac Monitoring Systems with Adaptive Interpretation

Our research concerns the problem of data queuing in telemedical non-uniformly reporting surveillance systems, recently introduced to cardiology. Automatic scheduling of reports was achieved with taking into consideration of two auxiliary data attributes in the information structure: the validity period and the priority, set individually for each ECG diagnostic measurement. The patient-side recorder-interpreter works in one of two reporting modes: in the delayed mode the transmission is deferred until packets are filled with valid data, while in the immediate mode diagnostic packets are transmitted as promptly as implied by sampling requirements. In the delayed reporting mode, the packet size lasts for 6 minutes of recording, while the wireless transfer session is completed within 10 seconds, allowing for reduction of 94% of required power. In the immediate reporting mode, the packet is collected within 4.63 seconds, which is still acceptable as real time monitoring.
