Aspects of Left Ventricular Morphology Outperform Left Ventricular Mass for Prediction of QRS Duration

Background: The knowledge of the case‐specific normal QRS duration in each individual is needed when determining the onset, severity and progression of the heart disease. However, large interindividual variability even of the normal QRS duration exists. The aims of the study were to develop a model for prediction of normal QRS complex duration and to test it on healthy individuals.
