Myocardial deformation as a predictor of right ventricular pacing-induced cardiomyopathy in the pediatric population.

Myocardial deformation imaging may be a clinically useful tool for the prediction of a decline in LV systolic function following pacemaker implantation. Abnormalities in A4C seem to appear before LVEF decline and as soon as 1-month postpacemaker implantation.
