SpletHyperacute T-waves are broad based, high and symmetric. Their duration is short; they typically disappear within minutes after a total occlusion in a coronary artery occurs (then of course, the ST segment will be elevated). T-wave inversion (inverted / negative T-waves) T-wave inversion means that the T-wave is negative. Splet08. dec. 2024 · The types of abnormalities are varied and include subtle straightening of the ST segment, actual ST-segment depression or elevation, flattening of the T wave, biphasic T waves, or T-wave inversion . In the absence of a clinical history or symptoms, T-wave abnormalities and flattened and depressed ST-segment changes are nonspecific.
