Key result

Novel SVM machine learning classifier detects 12-lead ECG cardiac irregularities with ~98% accuracy.

n=300

Why the study?

ECG predictors of reduced LVEF provide essential non-invasive triage capabilities for ACS patients, but no direct comparison of current ECG interpretation programs exists.

Key Points

To develop and evaluate a machine learning model using Support Vector Machine classifiers on 12-lead ECG signals to identify cardiac abnormalities and predictive markers of acute coronary syndrome.
Extracted time-domain, morphological, R-R intervals, and discrete wavelet transform features from ECG waveforms, focusing on the QRS complex and area under the T-wave.
Trained a Support Vector Machine (SVM) classifier to categorize cardiac beats into diverse rhythm abnormalities and conduction blocks.
Evaluated performance using 300 ECG signals obtained from the 12-Lead ECG PhysioNet Georgia Database.
The proposed Support Vector Machine technique achieved an overall diagnostic accuracy of 98.4% for identifying cardiac irregularities on the benchmark dataset.
The model attained a sensitivity of 97%, a specificity of 98.6%, and a precision of 95% across the 300 evaluated ECG signals.

Abstract

Background: Heart Failure is present in 1 out of 10 patients presenting Acute Coronary Syndrome. ECG predictors of reduced LVEF provide essential non-invasive triage capabilities, especially when echocardiography is not available instantly within reach. 12 lead ECG is easily accessible during the preliminary checkup of patient No direct comparison of the current electrocardiogram (ECG) interpretation program exists. Additional ECG training can improve accuracy. A systematic review and meta-analysis observed that across various training like pretraining and post-training and the median accuracy of ECG interpretation was 54% and 67% respectively [1]. Method: Here we proposed machine learning based approach to identify the highly predictive ECG Marker of Suspected Acute Coronary Syndrome i.e. the Ejection Fraction found in checkups [2]. This research proposes a modified technique for identifying cardiac abnormalities and QRS complexes, Leveraging Machine Learning and SVM (Support Vector Machine) classifiers. Results: The presented technique surpasses existing methods in both sensitivity and specificity achieving accuracy of 98.4 % for cardiac irregularities for the standard 12-Lead ECG Georgia database
