Clinical and echocardiographic correlates of intra-atrial conduction delay
EP Europace, 08/23/2011
Weijs B et al. – This study is the largest to investigate the relation between the atrial conduction time, underlying heart diseases, and echocardiographic parameters. Authors found that the PA–TDI was independently prolonged in patients with a history of AF, hypertension, valve disease, higher age, and a higher BMI. Signs of diastolic dysfunction, valve incompetence, and enlarged atrium or aortic root on the echocardiogram were associated with a prolonged PA–TDI. This suggests that early and aggressive treatment of hypertension, diastolic dysfunction, and obesity could prevent intra–atrial conduction delay.
