List of terms related to Persistent juvenile T-wave pattern

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Synonyms and keywords: Juvenile T waves

Overview

The Juvenile T-wave pattern refers to a normal electrocardiographic variant in which T wave inversions are present in the right precordial leads (V1, V2, and V3) along with an early repolarization pattern. Shallow T-wave inversion is usually found in the right precordial leads during infancy, and T wave rises upwards during childhood. If this inverted T-wave pattern sustained to adulthood, it is called persistent juvenile T-wave pattern.

Historical Perspective

The term Juvenile T-wave pattern was first introduced by American physician David Littman in 1946. [1]

Natural History, Complications, Prognosis

Juvenile T-wave resolves completely in 98% of the patients, and those that persist into adulthood demonstrate no adverse sequela.[2]

Differentiating persistent Juvenile T-wave pattern from other causes of T-wave inversion

  • QRS duration is equal or greater than 120 milliseconds
  • Absence of Q wave in leads I, V5 and V6
  • Monomorphic R wave in I, V5 and V6
  • T-wave deflection opposite to the major deflection of the QRS complex

Epidemiology and Demographics

  • Juvenile T-wave pattern is more commonly seen in black people—it has been shown in 10.8% of black population and 0.3% of white subjects.[4]
  • Juvenile T-wave pattern is more commonly found in females than males. [5][6]

Diagnosis

Electrocardiogram

Persistent juvenile T-wave pattern typically shows asymmetric T-wave inversion in V1-V3 without ST-segment elevation.

Treatment

Persistent juvenile T-wave pattern can be normalized by the following medications:

Medications [7] Dosage
Oral potassium bicarbonate-citrate 10 gm
Intravenous pro-banthīne 20–30 mg
