Sammanfattning
Machine learning models interpreting ECG signals enable scalability to increase the
number of patients examined for cardiac arrhythmia and hence contribute to democratize healthcare. In this thesis a machine learning model for detecting ectopic
heartbeat arrhythmias is developed and evaluated. The initial aim was to interpret
signals from mobile ECG devices but due to lack of data, the model was developed
and evaluated on the publicly available MIT-BIH Arrhythmia Database. The evaluation followed an inter-patient evaluation scheme to mimic the performance of the
model in real-world clinical settings. The proposed model design included ensemble learning between a convolutional neural network and a multilayer perceptron
network. The model was able to detect non-ectopic, supraventricular ectopic, and
ventricular ectopic heartbeats with a recall of 97 %, 62 %, and 78 %, respectively.
