Vector analysis of the movement of the epicardium has been used to calculate the energy efficiency of different parts of the left cardiac ventricle. The protocol based on the results of these calculations would allow the calculation of the potential power of myocardial contraction.
A method of invasive and non-invasive examination of epicardial motion was tested on domestic pigs (n=15). The invasive study employed a contact kinematic sensor of the epicardial wall motion, which determined the amplitude, velocity, and angular parameters of examined epicardial region. A non-invasive assessment of the epicardial kinematics based on… (More)
