title: The ability of mitral papillary muscle positions to explain QRS complex characteristics in humans.
abstract: Anatomical location of the conduction system may influence the characteristics of the depolarization and thus characteristics of the QRS complex. It is known that in the heart, there are electro-anatomical relationships, such as relationships among the molecular, genetic and anatomic components of the conduction system and papillary muscles. This review aims to discuss how knowledge of the electro-anatomical developmental relationships helps in understanding the known variability to be observed in the human electrocardiograms.
