Why the study?
Can age-based criteria for the RSR' complex in lead V1 distinguish normal subjects from patients with congenital heart disease?
Can age-based criteria for the RSR' complex in lead V1 distinguish normal subjects from patients with congenital heart disease?
Age-based criteria for the RSR' complex in lead V1 can successfully distinguish normal variants from congenital heart disease in 85% of cases.
May support age-based RSR' criteria in V1 for differentiation; leaves open prospective validation before clinical adoption.
An RSR' complex was present in lead V 1 in the electrocardiograms of 44 of 870 normal people from birth to 30 years of age; an overall incidence of 5 per cent. Analysis of the RSR' from these 44 patients demonstrated the importance of considering age when interpreting the RSR' complex. Criteria for distinguishing normal and abnormal RSR' complexes for various age groups was suggested. These criteria were 85 per cent successful in distinguishing the RSR' complex in patients with congenital heart disease from the RSR' complex in normal subjects.
