sup][1],[2],[3] It has been demonstrated that changes in atrial size and fibrosis cause dispersion of refractoriness and alterations in atrial conduction.
8 The degree of atrial dilation and the size of the ASD positively relate to changes in the atrial conduction time.
Prolonged atrial conduction is also a predisposing factor for the development of atrial flutter, where the mechanism for atrial arrhythmias is mainly due to the abnormal impulse conduction between the atria along interatrial pathways, primarily the Bachmann's Bundle, where atrial conduction times are increased.
The correlation between the presence of abnormalities in atrial conduction and paroxysmal AF induction is well documented (2).
Objective: The aim of our study was to investigate total atrial conduction time and left atrial (LA) mechanical function in patients with isolated coronary artery ectasia (ICAE).
Total atrial conduction time is measured as the time delay between the onset of the P-wave (preferably in lead II) of the surface electrocardiogram and the peak A'-wave on the tissue Doppler tracing of the left atrial (LA) lateral wall (PA-TDI duration).
Atrial fibrillation (AF) is known to induce atrial electrical remodeling (AER), which includes shortening, maladaptation, and increased dispersion of atrial effective refractory period (AERP) as well as decreased atrial conduction velocity (1, 2).
Recent findings showed that AF induces atrial electrical remodeling, increases dispersion of atrial effective refractory period and decreases atrial conduction velocity.
