found that intra-atrial and interatrial conduction times, such as electrophysiological parameters, were longer in patients with atrial arrhythmias, especially paroxysmal AF.
(6) on pediatric patients with hypothyroidism, we aimed to evaluate ventricular diastolic function, inter- and intra-atrial conduction delay and P wave dispersion in pediatric patients with type 1 DM.
We speculated that [P.sub.d] may be more dependent on inter and intra-atrial conduction disturbances as well as an inhomogeneous conduction of electrical impulses than the degree of left atrial dilatation itself.
The difference between PAs-PAl, PAs-PAt, and PAl-PAt were defined as left intra-atrial, right intra-atrial and interatrial EMD, respectively [7, 9].
Intra-atrial pressure increases rate and organization of waves emanating from the superior pulmonary veins during atrial fibrillation.
was very similar, but this investigation was conducted using delayed enhancement magnetic resonance imaging (DE-MRI) to estimate the degree of atrial fibrosis and atrial electromechanical delay (AEMD), a noninvasive echocardiographic method to measure inter- and intra-atrial conduction delays [22].
The intra-atrial septum was bowing to the left, appearing aneurysmal in nature.
Fibrosis of the atrial tissue leads intra-atrial conduction disturbances.
Two simple electrocardiographic markers, P wave maximal duration and P wave dispersion, have been used to evaluate the intra-atrial and inter-atrial conduction times and the inhomogeneous propagation of sinus impulses which are well-known electrophysiological characteristics of atria that prone to fibrillation.2,3 P dispersion is defined as the difference between the longest and shortest P wave durations recorded from 12-lead surface electrocardiogram (ECG) leads.
Transesophageal echocardiography (TEE) has been used for visualizing LAA to detect thrombus and intra-atrial masses and to diagnose LAA (1, 10, 13, 20).
