“…Tissue Doppler echocardiography may be used for this purpose because of its high temporal and spatial resolution. We found that ILCT detected by tissue Doppler echocardiography was higher in patients with lone paroxysmal AF compared to healthy control group [14]. There was no statistically significant difference in intra-right atrial and interatrial conduction times between the groups, and only ILCT was detected as an independent marker of paroxysmal AF in that study [14].…”

Merckx et al [15] demonstrated that tissue Doppler echocardiography can be used to measure total duration of atrial electrical activation which is valuable to detect patients with risk of AF development.…”

“…Specifically, greater atrial mass shortens the refractory period and delays conduction, which may increase the quantity of daughter wavelets. Deniz et al (26) suggested that TDI may be used to measure inter- and intra-atrial mechanical delays and that TDI may indicate an increase in left atrial electromechanical delay in PAF patients. Also, Ariyarajah et al (27) proposed that an interatrial block on ECG may be a novel predictor of embolic stroke.…”

Objective:The aim of this study was to evaluate the relationship between atrial electromechanical delay (EMD) measured with tissue Doppler imaging (TDI) and left atrial (LA) mechanical functions in patients with ischemic stroke and compare them with healthy controls.Methods:Thirty patients with ischemic stroke were enrolled into this cross-sectional, observational study. The control group consisted of 35 age- and gender-matched apparently healthy individuals patients. Acute cerebral infarcts of probable embolic origin were diagnosed via imaging and were confirmed by a neurologist. Echocardiographically, time intervals from the beginning of P wave to beginning of A wave from the lateral and septal mitral and right ventricular tricuspid annuli in TDI were recorded. The differences between these intervals gave the mechanical delays (inter- and intra-atrial). Left atrial (LA) volumes were measured using the biplane area-length method, and LA mechanical function parameters were calculated. Statistical analysis was performed using student’s t-test, chi-squared test, and Pearson’s test.Results:The laboratory and clinical characteristics were similar in the two groups. Increased left atrial EMD (21.36±10.38 ms versus 11.74±6.06 ms, p<0.001), right atrial EMD (13.66±8.62 ms versus 9.66±6.81 ms, p=0.040), and interatrial EMD (35.03±9.95 ms versus 21.40±8.47 ms, p<0.001) were observed in stroke patients as compared to controls. Active LA emptying volume and fraction and passive LA emptying volumes and fraction were similar between controls and stroke patients. Total LA emptying volumes were significantly increased in stroke patients as compared to healthy controls (33.19±11.99 mL/m2 versus 27.48±7.08 mL/m2, p=0.021).Conclusion:According to the results of our study, interatrial electromechanical delay may be a new predictor for ischemic stroke.
