One hundred normal Indian subjects were studied to establish the normal left atrial dimension (LAD), left atrial dimension cor­rected to body surface area (LA index) and left atrium to aorta ratio (LA/AO) for this population. Normal mean LAD was 21.9 ± 3.6 mm (12 mm to 30 mm). Elderly subjects had higher mean LAD (25.2 ± 3.6 mm). The LA index for adults was 14.1 ± 2.5 mm. LA index for younger subjects was higher because of low body sur­face area. Mean LA/AO was 0.95± 0.22;LA/AO greater than 1.17 is suggested as a criterion for LA enlargement.
