Precordial electrocardiograms in healthy adult Black subjects demonstrated no increased incidence of the T-wave inversion juvenile pattern, indicating identical standards for normality across races.
Cross-Sectional
Is there an increased incidence of T-wave inversion 'juvenile pattern' on precordial electrocardiograms in healthy adult Negroes compared to white subjects?
Normal precordial ECG standards are identical across races; T-wave inversion in Black adults should not be dismissed as a normal racial variant and warrants investigation for organic heart disease.
The T waves of the precordial electrocardiograms are upright in healthy adult white subjects. On the other hand, several reports have drawn attention to T-wave inversion "juvenile pattern" in adult Negroes free of organic heart disease. This study demonstrated no increased incidence of the "juvenile pattern" in healthy adult Negroes. The standards for normality are identical for both white and Negro. When abnormalities of the T wave are found in Negroes, an explanation other than that of race should be sought.
Greene et al. (Sun,) conducted a cross-sectional in Healthy adults. Precordial electrocardiogram vs. White subjects was evaluated on Incidence of T-wave inversion (juvenile pattern). Precordial electrocardiograms in healthy adult Black subjects demonstrated no increased incidence of the T-wave inversion juvenile pattern, indicating identical standards for normality across races.
