Figure 1 Diversity of Abnormal 12-Lead ECG Patterns in 5 Black Athletes

Diversity of abnormal 12-lead electrocardiographic (ECG) patterns in 5 black athletes characterized by (A) ST-segment depression in inferior leads, J-point elevation in right precordial leads, and diffuse T-wave inversions in a 21-year-old lineman; (B) deep symmetric T-wave inversions in V₁ to V₃ in a 21-year-old defensive back; (C) J-point elevation in right precordial leads, deep symmetric T-wave inversions in V₃ to V₆, and inferior T-wave inversions in a 22-year-old defensive back; (D) marked increased voltage (>40 mm in V₄) in a 21-year-old wide receiver; and (E) markedly increased voltage (>40 mm in V₄), J-point elevation in V₂ to V₃, and T-wave inversion in V₂ to V₄ in a 21-year-old wide receiver.
