Abstract : Abstract: This study aims at detecting cardiac arrhythmia which is found in a large population today because of the hypertension and lifestyle. When heart beat is irregular in a human being we can all that as cardiac arrhythmia. Cardiac diseases are a major reason of less life expectancy and so it is a crucial and severe health problem in today’s era. A framework based on Conventional neural network and BiLSTM-Bidirectional Long Short Term Memory networks are using here to classify the ECG signals and to detect Cardiac arrhythmia. Since ECG signals are time-series signals, this hybrid model is one of the best. CNN has different layers and through different steps CNN will do feature extraction while BiLSTM will capture long-term dependencies in ECG Signals, temporal frequencies in the heartbeat. ECG signals are classified and it will give the ouput as - Normal, Low risk, high risk. So CNN + BiLSTM together will work and detect abnormalities in ECG waveforms, learns heartbeat sequence and classify accurately thereby detect Cardiac arrhythmia earlier.

Keywords : Cardiac Arrhythmia Detection, Convolutional Neural Network (CNN), Bidirectional Long Short-Term Memory (BiLSTM), Time-Series Signal Analysis, ECG Classification.
