What is a symmetrical T wave?
The T-wave is normally slightly asymmetric since its downslope (second half) is steeper than its upslope (first half). Women have a more symmetrical T-wave, a more distinct transition from ST segment to T-wave and lower T-wave amplitude.
What does it mean when the T wave is inverted?
T wave inversions in the right chest leads may be caused by right ventricular overload (e.g., acute or chronic pulmonary embolism) and in the left chest leads by left ventricular overload (Chapter 7). Diffusely inverted T waves are seen during the evolving phase of pericarditis or myocarditis.
Why is the T wave upright on an ECG?
Furthermore, tall or wide QRS complex with an upright T wave is further suggestive of the posterior infarction. Wellens’ syndrome is caused by the injury or blockage of the left anterior descending artery, therefore resulting in symmetrical T wave inversions from V2 to V4 with depth more than 5 mm in 75% of the cases.
Is T wave inversion normal in females?
T-wave inversion in the anterior chest wall leads is relatively common in children and adolescents[9] but infrequently found in healthy adults and is considered as “normal variants”[4]. This pattern is more common in young females and young adults (1%-3%)[14,15].
Should I worry about abnormal T-wave?
Abnormalities of the T wave are associated with a broad differential diagnosis and can be associated with life-threatening disease or provide clues to an otherwise obscure illness.
Should I worry about inverted T waves?
Conclusions— T-wave inversions in right precordial leads are relatively rare in the general population, and are not associated with adverse outcome. Increased mortality risk associated with inverted T waves in other leads may reflect the presence of an underlying structural heart disease.
Should I worry about T wave inversion?
What does the T wave indicate?
The T wave on the ECG (T-ECG) represents repolarization of the ventricular myocardium. Its morphology and duration are commonly used to diagnose pathology and assess risk of life-threatening ventricular arrhythmias.
Can an inverted T wave be normal?
The T waves in leads III, aVL, and V1 were separately tested before inclusion into their respective lead groups, because an inverted T wave in these leads is considered normal, but the T waves in these leads can also be affected by different disease processes.
