In-depth ECG Analysis for the Extraction of Biomarkers of Cardiac Mechanical Dispersion

Left ventricular systolic dysfunction (LVSD) refers to impaired contraction of the left ventricle, and can lead to heart failure and death. Early identification of LVSD, which often remains asymptomatic for years, is therefore crucial to mitigate the associated risks through appropriate treatment. Echocardiographic screening of asymptomatic individuals is costly, requires access to experts, and the criteria for selecting potential high-risk individuals for screening remain unclear. Unlike echocardiography, the electrocardiogram (ECG) is a relatively low-cost procedure, routinely available and requiring little technical training to set up the examination and collect data, making it an interesting tool for early detection of LVSD.
