Research question and aims

This research aims to identify, on streaming data, abnormal hearth electric patterns, specifically those who are life-threatening, in order to be a reliable signal for Intensive Care Units to respond quickly to those situations. It also may be able to continuously analyze new data and correct itself shutting off false alarms. Primarily an experiment will be conducted using 2 main algorithms that use Matrix Profile in detecting context changes: SDTD and FLOSS. One uses whole data training and testing, and the other uses a streaming approach that is our main interest. The goal will be detecting the transition from normal to flutter/FA to normal condition with special attention to not rely on rhythm changes. Being this successful, a more generalistic approach will be attempted: to detect changes from normal to abnormal to normal conditions, with special attention to handle with disconnected leads or patient movements. Finally, this research can prove to be a good addition to the Matrix Profile method, using fading factors in order to reduce memory and space consumption, lowering the processor power needed, allowing this algorithm to be used in almost any device.
