T-wave inversions in the inferior and/or lateral leads and deep T-wave inversions occurred infrequently in athletes (1.5 and 0.8%, respectively) and were associated with a high prevalence of left ventricular hypertrophy or congenital cardiac anomalies. Despite intensive investigations, no athlete was...

catecholamine-mediated or due to histamine-induced myocardial ischemia. (Lui,[1993]) However, many clinicians maybe unaware of this ECG pattern caused by PE. It is essential to consider PE if QT prolongation and T-wave ...
Left ventricular pressure overload and complete left bundle branch block produce tall T waves in leads V1 and V2 as reciprocal change of T wave inversions in leads V5, V6. Peaked, symmetrical, tall T waves with narrow base are seen in hyperkalemia. Prominent and broad T waves with a prolo...

T wave The T wave reflects phase 3 of the action potential which represents the rapid ventricular repolarization. Normally the T wave is upright in leads I, II, and V5–V6 and inverted in lead aVR. The duration and amplitude of the normal T wave can vary, however, an amplitude >5 mm ...
The normal T-wave in adults is positive in most precordial and limb leads. The T-wave amplitude is highest in V2–V3. The amplitude diminishes with increasing age. As noted above, the transition from the ST segment to the T-wave should be smooth. The T-wave is normally slightly ...
Simultaneous T-Wave Inversions in Anterior and Inferior Leads: An Uncommon Sign of Pulmonary Embolism Pulmonary embolism (PE), a major cause of morbidity and mortality, remains an elusive diagnosis. Recently investigators have found a new electrocardiograph... Michael D. Witting MD, MS,Amal Mattu ...
Ischaemia(if dynamic or in contiguous leads) or Electrolyte abnormality, e.g.hypokalaemia(if generalised) Ischaemia Dynamic T-wave flattening due to anterior ischaemia (above). T waves return to normal once the ischaemia resolves (below). ...
Finally, we hypothesized that patients with non-STEMI and LBBB would more frequently have concordant T-waves, a presumed analogue to T-wave inversions in ECGs with normal conduction. Access through your organization Check access to the full text by signing in through your organization. Access ...
