Hello I am Philip Gemke and I am performing a master thesis about heart signals in the Division Data Science. I am also paramedic and have thereby big interest in applied bioinformatics. I am using algorithm and machine learning for classification of audiosignals of pediatric hearts to detect pathologies like holes int the heart muscle or not closing valves during heart beat. Additional I have some ideas about detection of ECG-changes in patient with heart attack, that I want to investigate to test my hypothesis, that a monitoring approach over a long period of time and serial ECGs can be used for automated ECG interpretation.
