“…In a previous study, we also demonstrated that ILCT and IACT is increased in patients with hypertension with diastolic dysfunction [24]. Interatrial conduction abnormality was shown to be present by tissue Doppler echocardiography in patients with heart failure due to left ventricular systolic dysfunction [25]. Prolonged interatrial conduction time in patients with severe left ventricular systolic dysfunction can affect left atrial remodeling and function [26].…”

“…9,33 Despite the intriguing findings of this study, certain limitations should be stressed. A recent study 34 proposed that a single-tissue Doppler imaging test might not be sufficient to characterize intraventricular dyssynchrony, and therefore may also be insufficient to determine intra-and interatrial synchronicity in one test.…”

The risk of developing atrial fibrillation is increased in patients with metabolic syndrome, but atrial conduction properties are uncharacterized in patients who have metabolic syndrome without atrial arrhythmia. We used tissue Doppler imaging to evaluate intra-and interatrial synchronicity in such patients. The imaging was performed in 145 patients with metabolic syndrome and 110 controls. Atrial synchronicity was determined from the intervals between the onset of the P-wave to the onset of the A-wave at the left atrial free wall (P-LA), interatrial septum (P-IAS) and right atrial free wall (P-RA). Intra-atrial synchronicity was defined as the differences between P-IAS and P-RA (RA synchronicity) and between P-LA and P-IAS (LA synchronicity). Interatrial synchronicity was defined as the difference between P-LA and P-RA. P-LA and P-IAS were significantly prolonged in the metabolic syndrome group relative to the control group (P-LA: 64.34 ± 13.99 vs. 55.35 ± 12.67, Po0.001; P-IAS: 36.49±12.39 vs. 31.55±11.61, P¼0.001), whereas P-RA showed no difference. As a result, this caused impaired intra-and interatrial synchronicity in patients with metabolic syndrome. Stepwise multivariate linear analysis revealed insulin resistance as an independent predictor of impaired intra-and interatrial synchronicity. Subgroup analysis indicated that there was no difference in atrial asynchrony between non-hypertensive and hypertensive subgroups in metabolic syndrome patients. In conclusion, patients with metabolic syndrome without atrial arrhythmia have impaired intra-and interatrial synchronicity. Insulin resistance has an important role in impaired atrial conduction in these patients.

“…In another study, using the tissue Doppler technique, atrial conduction times in patients with heart failure due to LV systolic dysfunction were found to be higher than the control group [14]. Yavuz et al [15] proved that inter and intra-atrial electromechanical delay times increase in hypertensive patients with diastolic dysfunction.…”

Background: Our main purpose in this study is to compare atrial (inter-atrial, intra-left atrial, intra-right atrial) wave on electrocardiography to the A' wave on tissue Doppler trace was accepted as the atrial conduction time (PA'). The PA' time difference between the mitral annulus of left ventricle (ML) and the tricuspid annulus of right ventricle (TL) was defined as inter-atrial electromechanical delay (IA-EMD), the PA' time difference between the ML and septal mitral annulus (MS) as intra-left electromechanical delay (ILeft-EMD), the PA' time difference between MS and the TL as intra-right electromechanical delay (IRight-EMD).Results: ILeft-EMD (21.8 ± 9.1 vs. 14.1 ± 4.9, p < 0.001), IRight-EMD (9.3 ± 6.8 vs. 5.9 ± ± 4.9, p = 0.03) and IA-EMD times (24.7 ± 11.2 vs. 11.9 ± 7.1, p < 0.001) were significantly longer in LAF patients. In multivariate regression analysis, using a model including age, gender and left atrium (LA) volumes, p = 0.012), p = 0.007) and LA volumes (OR 1.18, p = 0.005) were independent predictors of LAF. In LAF group, the frequency of AF episodes was significantly correlated with p < 0.001) and p < 0.004) (Cardiol J 2014; 21, 2: 138-143)
