Prominent Positive T Wave in V1, V2: Clinical Significance

Normal Variants vs. Pathological Findings

Prominent positive T waves in V1-V2 are often part of the normal spectrum of ECG findings, particularly in athletes and young individuals, according to the American College of Cardiology 1
Early repolarization patterns with J-point elevation, concave ST-segment elevation, and peaked T waves are present in up to 45% of Caucasian athletes and 63-91% of Black athletes, as reported by the American College of Cardiology 1

Age is an important factor when interpreting T waves in precordial leads: in adolescents under 16 years, T-wave patterns in anterior leads, including prominent T waves, are often normal "juvenile" patterns, as stated by the American College of Cardiology 1
In Black athletes, repolarization variants with J-point elevation and convex ST-segment elevation in anterior leads (V1-V4) are considered normal, according to the American College of Cardiology 1

The American College of Cardiology recommends assessing for other abnormal ECG findings that would require further investigation, such as ST-segment depression ≥0.5 mm in two or more contiguous leads 1
Pathologic Q waves (Q/R ratio ≥0.25 or ≥40 ms in duration in two or more leads) should be evaluated, as suggested by the American College of Cardiology 3
T-wave inversion ≥1 mm in depth in two or more contiguous leads (excluding leads aVR, III, and V1) should be considered, according to the American College of Cardiology 1

The American College of Cardiology advises not to confuse prominent positive T waves with T-wave inversion, which has different clinical implications 1
Prominent positive T waves in V1-V2 should not be confused with the Brugada pattern, which features ST-segment elevation with downsloping ST segment followed by negative T waves in V1-V3, as stated by the American College of Cardiology 1
