Giant T wave inversion.

Abstract
Symmetrical, deep, and narrow inversion of the T waves is usually due to ischemic heart disease and ventricular hypertrophy, particularly that of the right ventricle. A special type of giant T wave has been noted following Stokes-Adams attacks associated with complete heart block. The T waves are deep, blunt, broad, often bizarre, with a prolonged QTC and are usually maximal in leads V2 and V3. These changes are apparently particularly associated with syncope due to ventricular fibrillation. A slow heart rate with prolongation of ventricular diastolic filling time and ventricular distension may be an important component. However, cerebral disorders are probably the most important clinical cause of bizarre T wave distortion. It is likely that changes encountered in patients after Stokes-Adams attacks are basically cerebral in origin.
