Editor-In-Chief: C. Michael Gibson, M. The T wave represents the repolarization or recovery of the ventricles.

The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. The last half of the T wave is referred to as the relative refractory period or vulnerable period. Except in Hyperkalemia abnormality in T-wave alone is not diagnostic of any particular condition.

Usually, T-wave abnormalities can provide added evidence to support clinical diagnosis. In George Burch described T wave abnormalities as myocardial ischemia mimics in patients with a variety of acute cerebral insults.

His classic paper [2] published in May popularized the term Cerebral T waves. The T waves were described as large, were similar to those seen in early myocardial isehemia , and were reported to revert to normal with improvement of the clinical condition, or changed to the pattern of any underlying heart disease present prior to the intracranial insult.

They usually appear as diffuse giant T-wave inversions or large, upright T-waves or sometimes as flat T-waves. Dynamic T-wave flattening due to anterior ischaemia above. T waves return to normal once the ischaemia resolves below. Note global T-wave flattening in hypokalaemia associated with prominent U waves in the anterior leads V2 and V3.
