Research suggests that left atrium size as measured by an echo-cardiograph may be linked to cardiovascular disease. This is also a normal finding. National Library of Medicine Biatrial abnormality implies that the ECG indicates both left and right atrial enlargement; i.e a large P-wave in lead II and a large biphasic P-wave in lead V1. Secondary Mitral Valve Prolapse. The left atrial index was also higher in the hypertensive group, 2.18 +/- 0.45 versus 1.88 +/- 0.10 cm/m2 (p less than 0.05), and the left atrial-to-aortic root dimension ratio was significantly higher in the hypertensive group, 1.36 +/- 0.20 versus 1.17 +/- 0.07 (p less than 0.01). #mc_embed_signup { . at home i saw that it said possible left atrial enlargement but dr said nothing about this.
