Do new electrocardiographic criteria improve the recognition of atrial enlargement in patients with congenital and acquired heart disease?
The study introduces new criteria for identifying atrial enlargement on conventional scalar electrocardiograms, designed for routine clinical application.
New criteria for the electrocardiographic recognition of right atrial enlargement, left atrial enlargement, and combined atrial enlargement were studied in 110 patients with congenital and acquired heart disease. Precise physiologic data were available in all cases. The method of analysis was designed for application to conventional scalar electrocardiography and hence can be used without modification for routine clinical purposes.
Macrúz et al. (Thu,) studied this question.
