Index of variance versus duration of QRS complex for the diagnosis of mechanical left ventricular leakage
Comparison of sensitivity, specificity and predictive values in patients undergoing strain echocardiography to measure mechanical dispersion, QRS duration and index of variance through the Synchromax®method.

The index of dyssynchrony has a marked dependence on the mechanical dyssynchrony of the left ventricle.

Is traditional resynchronization therapy obsolete? Is para-Hisian stimulation the new paradigm?
In the early days of heart stimulation the main concern was the maintenance of an adequate heart rate, given the absence of demonstrated deleterious effects during the acute period. The classic site of stimulation in the right ventricle (DV) was the apical region. In the 1980s some harmful effects of DV apex stimulation began to be described.
