These ECG findings in athletes are considered normal, physiological adaptations to regular exercise and do not require further evaluation (box 1). Convex (‘domed’) ST segment elevation combined with T ...

Here, we consider the potentially-underlying reasons for these annoying minimal ECG changes and explore various clinical situations that could cause T waves and ST segments to deviate from normal.

There is low voltage in leads V4 through V6 (unlike limb lead reversal which has normal voltage in these leads, but negative QRS in lead I). Hypokalemia causes U waves in the ECG seen as a ...

Less commonly, SCD manifests without prior disease symptoms in individuals with structurally normal ... ECG) between ventricular depolarization (reflected by the QRS complex) and repolarization (T ...

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...

Although a normal QT interval imparts a much lower risk of life ... 16 Finally, one must keep in mind that the QTc is not the only finding available on the 12-lead ECG. Specific T-wave and ST-segment ...
