Normally, there is no electrical activity (flat ECG) between ventricular depolarization (reflected by the QRS complex) and repolarization (T wave), corresponding to the ST segment, because all ...

Note: The ECG changes of pericarditis must be distinguished from those of early repolarization. The ST elevation seen in early repolarization is very similar: diffuse and concave upward.

A left ventricular aneurysm can be diagnosed on ECG when there is persistent ST segment elevation occurring 6 weeks after a known transmural myocardial infarction (usually an anterior MI).

High vagal tone in athletes results in bradycardia and repolarization anomalies on the resting ECG. Bradycardia permits ... characterized by modest left ventricular (LV) wall hypertrophy, as ...
