Juvenile T waves (a study of 100 normal subjects)
Indian Journal of Physiology and Pharmacology
|October 1, 1984
Summary
The juvenile T wave inversion pattern in electrocardiograms is common in young, healthy Indians. Factors like lower weight-to-height ratio and income influenced its occurrence in this study.
Area of Science:
- Cardiology
- Clinical Electrocardiography
- Public Health
Background:
- The "juvenile pattern" of T wave inversion in precordial leads is a recognized electrocardiogram finding.
- Understanding its prevalence and associated factors in diverse populations is crucial for accurate interpretation.
Purpose of the Study:
- To investigate the incidence of the juvenile T wave inversion pattern in a healthy Indian cohort.
- To explore potential correlations between this pattern and demographic/anthropometric factors.
Main Methods:
- Electrocardiogram (ECG) analysis of 100 healthy Indian individuals across a wide age range (0-70 years).
- Assessment of anthropometric data (weight/height ratio) and socioeconomic factors (annual income).
- Limited use of Exercise Electrocardiogram (ECC) to observe T wave changes.
Main Results:
- The juvenile T wave inversion pattern was identified in 25% of subjects up to 19 years of age.
- A higher incidence was noted in individuals with a weight/height ratio below 30%.
- Maximum incidence (48%) was observed in the income group earning Rs. 15,000/- annually.
Conclusions:
- The juvenile T wave inversion pattern shows a notable incidence in younger, healthy Indian individuals.
- Anthropometric and socioeconomic factors may be associated with the presence of this ECG pattern.
- Further research is warranted to fully elucidate the clinical significance of these associations.
