Value of the electrocardiogram in detecting left ventricular dysfunction in asymptomatic patients with aortic regurgitation

Abstract

This study demonstrates the value of the electrocardiogram at rest, but preferably with effort, to detect LV dysfunction in patients with AR. We suggest that the R 6:S 2 time relation is useful in evaluation of AR and in follow-up of patients. When the test becomes abnormal, LV dysfunction is present. Further studies are needed in order to confirm this simple test, to correlate the findings with other investigative techniques, and to investigate reversibility of LV dysfunction after surgical management.
