Webb21 mars 2024 · The T wave that follows the QRS complex represents the repolarisation of the ventricular myocardium, ready for the next heartbeat. Atrioventricular conduction abnormalities ECG nomenclature First-degree heart block First-degree AV block is defined as a PR interval longer than 0.2 seconds [ 1] . Webb22 sep. 2024 · Ischemic T-wave inversions are classically symmetric. Often, they appear in an anatomic (regional) pattern. Even minor T-wave inversions may be significant if they are disproportionate to the voltage of the QRS complex. T-wave inversions may signify acute intra-cerebral hemorrhage.
