Evaluation of Atrial Electromechanical Delay and Its Relationship to Inflammation and Oxidative Stress in Patients with Chronic Obstructive Pulmonary Disease

Abstract

This study shows that atrial electromechanical delay intervals are prolonged in patients with COPD. Prolongation of atrial electromechanical delay measured from lateral tricuspid annulus was independently related with FEV1 /FVC ratio in these patients.

The Role of the Atrial Electromechanical Delay in Predicting Atrial Fibrillation in Myotonic Dystrophy Type 1 Patients

“…It has been studied in some clinical conditions. Deniz et al ., in a study comparing tissue Doppler echocardiography and electrophysiological study, found a moderate correlation between ILCT‐echo and ILCT‐eps, and demonstrated that tissue Doppler echocardiography can be used for the measurement of interatrial and intraleft atrial conduction times. Previous studies evaluated the predictive role of intraleft atrial electromechanical delay for paroxysmal atrial fibrillation recurrence after cardioversion, lone atrial fibrillation attack, new‐onset AF after acute myocardial infarction, occurrence of atrial arrhytmias in adult patients with congenital heart diseases .…”

Atrial Septal Aneurysms and Supraventricular Arrhythmias: The Role of Atrial Electromechanical Delay

“…Atrial electromechanical delay duration is the sum of impulse propagation from sinus node to the atria and atrial electromechanical coupling duration. It has been studied in some clinical conditions . Deniz et al., in a study comparing tissue Doppler echocardiography and electrophysiological study, found a moderate correlation between ILCT‐echo and ILCT‐eps, and demonstrated that tissue Doppler echocardiography can be used for the measurement of interatrial and intra‐left atrial conduction times.…”

Impact of Continuous Positive Airway Pressure Therapy on Atrial Electromechanical Delay in Obesity‐Hypoventilation Syndrome Patients

“…Previous studies have demonstrated that prolonged intra-and inter-atrial conduction times and inhomogeneous propagation of sinus impulses would be the characteristics of increased AF risk in various clinical conditions during sinus rhythm. 27 It has been studied in some clinical conditions, [28][29][30][31] and it was found that AEMD is significantly correlated with the prolonged maximum P-wave duration, P-wave dispersion, and degree of histopathological changes. [32][33][34] Previous studies evaluated the predictive role of intra-left atrial electromechanical delay for paroxysmal atrial fibrillation recurrence after cardioversion, [35][36][37] lone atrial fibrillation attack, 38 new-onset AF after acute myocardial infarction, 39 occurrence of atrial arrhythmias in adult patients with congenital heart diseases, 40 myotonic dystrophy type 1, 41 and atrial septal aneurysm.…”
