TABLE 6:

The characteristics of publicly available echocardiography datasets. HF (heart failure), CAD (coronary artery disease), DCM (dilated cardiomyopathy), MI (myocardial infarction), SD (standard deviation), LV (left ventricle), EF (ejection fraction), ESV (end-systole volume), EDV (end-diastole volume).
