Abstract: Provided here is an apparatus, a computer program product, and a method for providing a corrected QT interval (QTc) measurement from electrocardiograma method comprises step of receiving electrocardiogram at least one electrocardiogram (ECG) source; cleansing said electrocardiographic data; extracting ECG segments from cleansed electrocardiogramased on ECG channel electrode(s) of interest; providing one or more baseline models trained with annotated segments to generate interpreted heart rhythm/rate based on the extracted ECG segments; selecting an image processing model based on the interpreted heart rhythm/rate; and applying the selected image processing model to the cleansed electrocardiogramhere the image processing model outputs the QTc measurement.
