Evaluating functional capacity, and mortality effects in the presence of atrial electromechanical conduction delay in patients with systolic heart failure

Abstract: Objective:Atrial functions are relatively suppressed in heart failure (HF). We aimed to investigate the associations of intra- and inter-atrial electromechanical conduction delay (EMCD) with functional class and mortality over a 12-month follow-up period.Methods:The prospective study included 65 patients with systolic HF and 65 healthy subjects with normal sinus rhythm. Left ventricular (LV) systolic functions and left atrial (LA) dimensions and volumes were evaluated by transthoracic echocardiography. Tissue … Show more

“…The time was defined as PA and was obtained from the lateral mitral annulus (PA lateral), septal mitral annulus (PA septal) and RV tricuspid annulus (PA tricuspid) from the starting of the P wave in the surface ECG to the beginning of the late diastolic wave (Am). While intra-atrial EMD was PA septum minus PA tricuspid, the inter-atrial EMD was calculated and defined as PA lateral minus PA tricuspid [24,25] (Figure 1).…”

“…The time interval from the onset of the P-wave on surface ECG to the beginning of the late diastolic wave (Am), which is called PA, was gained from the lateral mitral annulus (PA lateral), septal mitral annulus (PA septal), and RV tricuspid annulus (PA tricuspid) ( Figure 1 ). The difference between PA septum and PA tricuspid (PA septum − PA tricuspid) was identified as intra-atrial electromechanical delay while the difference between PA lateral and PA tricuspid (PA lateral − PA tricuspid) was identified as interatrial electromechanical delay [ 27 , 28 , 29 ].…”

“…We excluded patient with QRS duration > 120 ms in this study. Beeumen et al 18 and Bilgin et al 19 studied heart failure population with reduced and mid-range ejection fraction (LVEF < 50%) but only half of study population consist of ischemic cardiomyopathy (45 % and 54%).…”

“…Study conducted by Bilgin et al 19 used a different method to measure AEMC interval by measuring time interval from onset of P wave in surface electrocardiogram to peak instead of initial A wave on TDI echocardiography called peak PA interval. Study conducted by Lee et al showed that both method of AEMC interval measurement (initial PA and peak PA ) had approximately the same ability to discriminate paroxysmal AF from control (Area Under Curved, AUC PA initial 0.743 Vs AUC PA peak 0.718).…”
