Abstract

A machine learning-based heart health monitoring model, named H2M, was developed. 24-hour electrocardiogram (ECG) data from 112 professional firefighters was used to train the proposed model. The model used carefully designed multi-layer convolution neural networks with maximum pooling, dropout, global maximum pooling to effectively learn the indicative ECG characteristics. H2M was benchmarked against three existing state-of-the-art machine learning models. Results showed the proposed model was robust and had an overall accuracy of approximately 94.3 %. A parametric study was conducted to demonstrate the effectiveness of key model components. An additional data study was also carried out and it was shown that using non-firefighters' ECG data to train the H2M model led to a substantial error of 40 %. The contribution of this work is to provide firefighters on-demand, real-time heart health status to enhance their situational awareness and safety and to help reduce firefighters' deaths and injuries due to sudden cardiac events.
