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.

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 ...

The most common ECG finding of an acute pulmonary embolism ... from hypocalcemia has a lengthened ST segment, then normal-appearing T wave. Wellen’s phenomenon occurs from a proximal left ...

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 lines are comprised of three main parts: In normal sinus rhythm, the P-P interval (the time between consecutive P waves ...

uw.edu The most substantive change is the introduction of a ‘yellow’ box or list of borderline ECG findings in which two or more borderline findings warrant additional evaluation (figure 1).

Positive and negative peaked T waves with high amplitude were detectable in the preclinical 12-lead ECG. Additionally, a first-degree AV block was present (P waves merging with preceding T waves).
