Asynchronous electrical activation of the ventricles, as during left bundle branch block (LBBB) and during ventricular pacing, is associated with abnormal, locally different contraction patterns (1-3) and deficiencies in perfusion and glucose uptake

The contributions of changes in primary systolic and diastolic properties, limitations of contractile reserve, and alterations in energy efficiency to the left ventricular dysfunction seen with chronic pacing tachycardia were investigated. Seven dogs

The effects of different pacing protocols on left ventricular (LV) torsion were evaluated over the full cardiac cycle. A systolic and diastolic series of magnetic resonance imaging (MRI) scans were combined and used to calculate the torsion of the LV

The temporal evolution of three-dimensional (3-D) strain maps derived from magnetic resonance imaging (MRI) tagging were used to noninvasively evaluate mechanical activation in the left ventricle (LV) while seven canine hearts were paced in situ from

We quantitatively compared the extrasystolic and postextrasystolic responses of the right ventricle and left ventricle of the same heart, which have vastly different geometries, architectures, and muscle masses. We studied nine isolated, supported ca
