Predictive value of atrial electromechanical delay for atrial fibrillation recurrence

Abstract

p = 0.03). Conclusions: Our results suggest that AEMD is associated with an increased risk of recurrence of AF within 1-month. These data may have implications for the identification of patients who are most likely to experience substantial benefit from cardiversion therapy for AF. (Cardiol J 2013; 20, 6: 639-647)

Correlation between increased atrial expression of genes related to fatty acid metabolism and autophagy in patients with chronic atrial fibrillation

“…The intra-atrial EMD is the time delay from the electrical activation to the actual motion of the atrial myocardium, and a delayed intra-atrial EMD indicates excitation-contraction uncoupling in the atrium. Prolonged intra-atrial EMD after cardioversion was reported to predict AF recurrence in patients with persistent AF, and histopathological changes characterized by myocardial fibrosis in the atrium appear to be a major determinant of the prolonged intra-atrial EMD [21].…”

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

“…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. 42…”

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.…”
