Information Flow and Data Reduction in the ECG Interpretation Process

In result of ECG interpretation process the diagnostic outcome summarizes all the principal information included in the raw recording. This process is investigated in this paper in data flow and data reduction aspects being of particular importance for implementation of distributed ECG interpretation in a wireless network. The detailed analysis of existing software and cardiologists societies guidelines reduces the whole interpretation process to the network of modules interconnected by data busses. Each module is then described by the computational reliability and by expected data streams at its inputs and outputs, from which the average data reduction ratio is computed. These parameters are consequently used for a design of interpretation architecture improving the diagnostic reliability and oriented to appropriate task sharing between the remote wearable recorder and the interpretive center
