Key result
A Machine Learning C5.0 algorithm using six ECG variables achieved a diagnostic accuracy of 71.4% (95% CI 65.5-80.2) for detecting left ventricular hypertrophy, surpassing the Romhilt-Estes score (61.3%).
Why the study?
ECG prediction of left ventricular hypertrophy is limited by low accuracy and sensitivity, prompting investigation into whether a machine learning algorithm could optimize ECG detection of echocardiographic LVH.
Does a Machine Learning C5.0 algorithm improve the diagnostic accuracy of ECG for detecting left ventricular hypertrophy compared to the Romhilt-Estes score?
