Automated quantitative assessment of QRS fragmentation can improve non-invasive risk stratification

Objectives: Fragmented QRS (fQRS) on a 12 lead electrocardiogram is associated with all-cause mortality and sudden cardiac death. Currently, the appreciation of fQRS on the 12 lead ACG is based on a visual assessment creating potential bias by inter- and intra-observer variability. With this subjective technique additional information about the morphology of the notches in fQRS is also neglected. We aimed to develop an automated quantitative assessment of fQRS.
