Existing rules-based automated heart monitoring systems are less reliable than trained cardiologists.
"Electrocardiograph records electrical signal from 12 different leads and patterns in the electrical behavior such as time intervals and voltage values, presence of ST elevation etc for each beat to diagnose the risk of developing heart attack. Currently there are pre-defined rules limited to the input of a few signals. Using machine learning, hidden patterns can be identified to build better models in predicting the risk of heart attack. Two German researchers have developed a CNN based model which has shown promising results."
"Recurrent neural networks have been successfully applied to time series classification problems" "Convolutional networks for time series classification and applied to the UCR Time Series Classification Archive datasets. Also used a sliding window approach similar to the one applied in this work and feed differently downsampled series into a multi- scale convolutional neural network also reaching state-of-the- art results on UCR datasets" "Models were implemented in TensorFlow"
"Trained using UCR Time Series Classification Archive" Testing on 549 records from 290 subjects
Stage 1 testing resulted in 93.3% sensitivity and 89.7% specificity, evaluated with 10-fold cross validation, which is the performance level of human cardiologists.
