A proposed method for automated diagnosis of various diseases based on heart rate variability (HRV) analysis and machine learning. HRV analysis – consisting of time-domain analysis, frequency-domain analysis, and nonlinear analysis – is employed because its resulting parameters are unique for each disease and can be used as the statistical symptoms for each disease, while machine learning techniques are employed to automate the diagnosis process. The input data consist of electrocardiogram (ECG) recordings. The proposed method is divided into three main steps, namely dataset preparation step, machine learning step, and disease classification step. The dataset preparation step aims to prepare the training data for machine learning step from raw ECG signals, and to prepare the test data for disease classification step from raw RRI signals. The machine learning step aims to obtain the classifier model and its performance metric from the prepared dataset. The disease classification step aims to perform disease diagnosis from the prepared dataset and the classifier model. The implementation of data preparation step is subsequently described with satisfactory result.

This model was designed for classifaction the signal quality of the dynamic ECGs collected by wearable devices. In order to avoid the misjudgment of manually designed features on ECG data and improve the classification accuracy, we designed one deep learning model combined the residual module and recurrent module. The signal qulaity was classcified to three categories: good (label:0) \ medium (label:1) \ bad (label:2).

ELEC 301 final project: ECG signal processing and classification

Deep Learning Approach on Automatic Classification of Depression using ECG and EDA physiological signals.

Premature ventricular contraction(PVC) is among the most frequently occurring types of arrhythmias. Along with other cardiovascular diseases, it may easily cause hazardous health conditions, making PVC detection task extremely important in cardiac care. However, the long-term nature of monitoring, sophisticated morphological features, and patient variability makes the manual observation of PVC an impractical task. Existing approaches for automated PVC identification suffer from a range of disadvantages. These include domain-specific handcrafted features, usage of manually delineated R peaks locations, tested on a tiny sample of PVC beats(usually a small subset of MIT-BIH database). We address some of these drawbacks in proposed framework, which takes a raw ECG signal as an input and localizes R peaks of the PVC beats. It consists of two neural networks. The first one is an encoder-decoder architecture that localizes the R peak of both Normal and anomalous heartbeats. Provided R peaks positions, our CardioIncNet model, adopted for ECG signal data, does the delineation of healthy versus PVC bits. We have performed the extensive evaluation of our pipeline with both single- and cross-dataset paradigms on three public datasets. Our approach results in over 0.99 and 0.979 F1-measure on both single- and cross-dataset paradigms for R peaks localization task and above 0.96 and 0.85 F1 score for the PVC beats classification task.

Classification of 3 types of Heart failures using Convolutional Neural Networks with a Graphical User Interface

An electrocardiogram (ECG) is a medical assessment tool used to observe heart functionality based on its continuous electrical activity. Each heart beat is stimulated by an electrical impulse that causes the muscle to contract and pump blood through the body. When this impulse is recorded over time, it produces an ECG pattern, which can be used to detect normal or irregular heart activity. This project aims to evaluate the effectiveness of wavelets for extracting multi-scale features in sequence based classification. Recurrent Neural Networks (RNNs) are trained to classify ECG heart beats 20 2018 within a time series ECG signal. Experiments using (one or more) benchmark datasets will be used to test the effectiveness of combining models drawn from various time resolutions. This work could eventually be used in Computer Aided Diagnosis, where the interpretation of ECG signals is done electronically and potentially more objective than manual interpretation.
