An Ensemble of Deep Recurrent Neural Networks for P-wave Detection in Electrocardiogram

ICASSP 2019accepted

Detection of P-waves in electrocardiogram (ECG) signals is of great importance to cardiologists in order to help them diagnosing arrhythmias such as atrial fibrillation. This paper proposes an end-to-end deep learning approach for detection of P-waves in ECG signals. Four different deep Recurrent Ne…
