Mutual Information Reveals Non-linear Relationships between Electrocardiographic Conduction or Repolarization Indices and Mechanical Dispersion by Speckle-Tracking Echocardiography in the General Population

Mutual Information Reveals Non-linear Relationships between Electrocardiographic Conduction or Repolarization Indices and Mechanical Dispersion by Speckle-Tracking Echocardiography in the General Population

Electrical inhomogeneities can lead to regional heterogeneity in left ventricular contraction. We investigated the correlation between electrocardiographic parameters of conduction and/or repolarization and myocardial longitudinal strain-derived parameters in a general population. Mean and dispersio...
