Imaging the coronary artery: is it really normal? How to avoid common echocardiographic pitfalls.

Coronary artery anomalies in the absence of structural heart defects are rare with an estimated prevalence of 0.6% to 1.2% in the general population.1 Although the anomalous left coronary artery (LCA) from the right cusp is quite rare (0.03%–0.05% estimated prevalence2), it is frequently associated with sudden cardiac death, especially when intramural.3 A similar presentation has been described...

QT interval: how to measure it and what is "normal".

Abnormally long and short QT intervals have been shown to be associated with an increased risk for life-threatening ventricular arrhythmias and sudden cardiac death. In recent years, various methods for QT-interval measurement have been developed, including individual-based corrections for repolarization duration, quantitative assessment of repolarization morphology, correction for repolarizati...
