Description

ECG Signal Classification using CWT and NN

Objective:

The main objective of this project is to identify and classify the heart abnormalities in an ECG signal. Based on the peak amplitude values can perform the classification operation.

ABSTRACT

Cardiac arrhythmia indicates the abnormal electrical activity of the heart that can be a great threat to humans. So it needs to be identified for clinical diagnosis and treatment. Analysis of ECG signal plays an important role in diagnosing cardiac diseases. An efficient method of analyzing ECG signal and predicting heart abnormalities have been proposed in this paper. In the proposed scheme, the collected ECG Signal Database will Convert 1D ECG signals to Images using CWT scalogram and classify with Transfer Learning via pre-trained Alex Net deep CNN. The goal is to train a CNN to distinguish between Arrhythmias(ARR), Congestive Heart Failure (CHF), and Normal Sinus Rhythm (NSR). The ECG Signals are obtained from 162 ECG recordings from three Physio Net databases

EXISTING SYSTEM:

SVM classifier
K means clustering

DRAWBACKS:

High Computational load
Poor discriminatory power
Less accuracy in classification

PROPOSED SYSTEM:

A CNN passes an image through the network layers and outputs a final class. The network can have tens or hundreds of layers, with each layer learning to detect different features. Filters are applied to each training image at different resolutions, and the output of each convolved image is used as the input to the next layer. The filters can start as very simple features, such as brightness and edges, and increase in complexity to features that uniquely define the object as the layers progress.
