Background

Delayed atrial conduction time, as measured by tissue doppler, is an independent predictor of new onset or recurrent atrial arrhythmias. The aim of this study was to evaluate the atrial conduction time and cardiac mechanical function among patients with early stage (stage I-II) chronic obstructive pulmonary disease(COPD).

Methods

Study consisted of 84 (35 female, 49 male, mean age 45,31 ± 12 years) patients with early stage COPD and 41 healthy subjects. Pulmonary function tests,12 lead surface ECG and echocardiographic examination were performed and recorded. P wave changes on surface ECG, minimum (P (min)) and maximum (P (max)) duration of P wave and its difference as P wave dispersion (P (wd)) were measured and recorded. Atrial electromechanic delay (AEMD) was calculated from colored-TDI recordings.
