Sudden death is a possible occurrence for newborns younger than 1 year with severe aortic coarctation (CoA) before surgical correction. Basic research and animal experiments have shown electrophysiologic changes during mechanical ventricular pressure overload. The current study aimed to evaluate the effect of severe CoA on the heterogeneity of ventricular repolarization by examining corrected Electrocardiographic Repolarization Complexity and Abnormality Predict All-Cause and Cardiovascular Mortality in Diabetes The Strong Heart Study Peter M. Okin, 1Richard B. Devereux, Elisa T. Lee,2 James M. Galloway,3 and Barbara V. Howard4 Type 2 diabetes is associated with increased risk of cardiovascular (CV) and all-cause mortality. Although
Heterogeneity of ventricular repolarization is considered to provide an electrophysiological substrate for malignant arrhythmias. QTc dispersion (QTc-D) and JTc dispersion (JTc-D) are electrocardiographic parameters indicative of heterogeneity of ventricular repolarization. Assessment of the individual risk for sudden death in patients with Multi-channel magnetocardiography (MCG) is a sensitive technique to map spatial ventricular repolarization with high resolution and reproducibility. Spatial ventricular repolarization heterogeneity measured by MCG has been shown to accurately detect and localize myocardial ischemia. Here, we explored whether these measurements correlated with cardiovascular risk factors in patients with type ?id=/

The most often used ECG markers for measuring repolarization heterogeneity include TpTe and QT dispersion (QTD). TpTe is calculated by measuring the interval from the peak of the T wave to its :// The earliest part of the repolarization is the repolarization of the epicardial action potential corresponding to the peak of the T wave.
The last part of the repolarization is the repolarization of the M cells corresponding to the end of the T wave. Thus, the Tp-e interval can be a marker of total dispersion of repolarization [31,32].

and assessment if it is It has become increasingly apparent that repolarization heterogeneity is present in a variety of cardiovascular diseases /_Electrocardiographic_Early_Repolarization. Early repolarization syndrome (ERS) refers to patients with ERP who have survived idiopathic ventricular fibrillation (VF).
A prevalent explanation for ERP is regional heterogeneity in the dispersion gradient of myocardial refractoriness, prompted by a net outward shift in repolarizing current and predisposing to phase 2 reentry, allowing a /electrocardiographic-early-repolarization-a-scientific-statement.
Ventricular repolarization continues to be an enigma to clinical cardiologists and cardiac electrophysiologists. On the one hand, a century of experience has documented an association between abnormal T-wave morphology, QT prolongation and dispersion, T-wave alternans, and nonspecific ST-T waves with arrhythmia risk or negative prognostic outcome.
On the other hand, recent advances in Electrocardiographic early repolarization is associated ST‐segment, removal of a study reduces heterogeneity significantly.
