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

Abstract

Our results showed that the echocardiographic AEMD indices (intra-left and inter-AEMD) and the PD were significantly increased in healthy ASA subjects without interatrial shunt. PD and AEMD represent noninvasive, inexpensive, useful, and simple parameters to assess the SVAs' risk in ASA patients.

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

“…It has been studied in some clinical conditions, and it was found that AEMD is significantly correlated with the prolonged maximum P‐wave duration, P‐wave dispersion, and degree of histopathological changes . Previous studies evaluated the predictive role of intra‐left atrial electromechanical delay for paroxysmal atrial fibrillation recurrence after cardioversion, lone atrial fibrillation attack, new‐onset AF after acute myocardial infarction, occurrence of atrial arrhythmias in adult patients with congenital heart diseases, myotonic dystrophy type 1, and atrial septal aneurysm …”

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

“…[18][19][20][21][22][23][24][25][26] The atrial-electromechanical-delay (AEMD) is an echocardiographic parameter correlated with the supraventricular arrhythmias (SVAs) onset in several clinical conditions. [27][28][29][30][31][32] The aim of the present study was to determine whether echocardiographic noninvasive indicators of atrial conduction heterogeneity (atrial electromechanical delay) may predict the paroxysmal atrial fibrillation onset in DM1 patients with conserved systolic and diastolic cardiac function.…”

The predictive value of intra‐left atrial mechanical delay for 1‐year recurrence of atrial fibrillation after catheter ablation: A clinical follow‐up study using dual Doppler echocardiography

“…11 Therefore, normal subjects exhibit physiological atrial mechanical delay. 22 In addition, previous studies have shown that patients with AF exhibited increased atrial mechanical delay, especially in patients with AF recurrence. [15][16][17] Furthermore, prolonged atrial mechanical delay has been shown to be associated with type 1 diabetes mellitus, 18 heart failure, 19 mitral stenosis, 20 and heart transplantation 21 as well as a higher incidence of supraventricular arrhythmias.…”
