Key result
Age, sex, and blood pressure link to abnormal ECG features, including ST depressions in females.
Why the study?
Electrocardiographic abnormalities and their relationships to constitutional characteristics, blood pressure, and serum cholesterol in a large religious isolate population were not well characterized.
Population
1,303 men and 1,348 women past 15 years of age in a large religious isolate
Comparison
ECG abnormalities related to constitutional characteristics, blood pressure, and serum cholesterol
Design
Cross-sectional survey with Minnesota Code ECG classification

In a large population survey, abnormal ECG features were significantly associated with age, sex, and blood pressure, highlighting the need for age and sex stratifications in clinical ECG interpretation.
Goldbarg et al. (1970) reported a cross-sectional. Constitutional characteristics, blood pressure, and serum cholesterol was evaluated on Electrocardiographic abnormalities (Minnesota Code). Abnormal ECG features were associated with age, sex, and blood pressure, with ST-segment depressions more common in females (P<0.005) and increased R-wave amplitude in males (P<0.005).
