Overview
The Juvenile T-wave pattern refers to a normal electrocardiographic variant in which T wave inversions are present in precordial leads V1, V2, and V3 along with an early repolarization pattern. Shallow T-wave inversion is usually found in the right precordial leads (V1-V3) during infancy. T wave then rises upwards during childhood. If this inverted T-wave pattern sustained to adulthood, it is called persistent juvenile T-wave pattern.
Natuarl History, Complications, Prognosis
Juvenile T-waves may persists into adulthood with no adverse sequela.
Differentiating persistent Juvenile T-wave pattern from other causes of T-wave inversion
Persistent juvenile T-wave inversion must be differentiated from other diseases that cause T-wave inversion, such as:
- Arrhythmogenic RV dysplasia should be suspected in this cohort if the T wave inversion persists beyond lead V1 in a post pubertal male athlete
- Cerebrovascular accidents can cause deep widely splayed T waves referred to as cerebral T waves
- Ischemic heart disease including non ST segment elevation MI or prior MI
- Left bundle branch block, it is normal for the T wave to be inverted if the QRS complex is upright
- Pulmonary embolism, particularly in the anterior precordium
