May aid ECG interpretation in young women; extends normative references but leaves open prospective validation.

Investigate the characteristics of electrocardiograms in normal women and analyze lead IV's relation to standard leads.
Analyzed electrocardiograms of 50 physically fit women aged 20-27.
Selected from an initial group of 100 based on normal height and weight ratios.
Focused on lead IV using specific electrode placements as recommended by cardiac guidelines.
Found consistent patterns in electrocardiogram readings across the participants.
Lead IV showed distinct features correlated with standard leads.
Data may support health assessments related to fitness in young women.

Population

50 normal women students between the ages of 20 and 27, physically fit with normal weight-height relation, attending the Royal Free Hospital.

Intervention

Electrocardiogram analysis including lead IV R

Outcome

Electrocardiogram characteristics of lead IV and its relations to the three standard leadssurrogate

This study describes the normal electrocardiographic features, with a special focus on lead IV R, in a cohort of healthy young women.

Hoskin et al. (1940) studied this question.
