Background: Heart arrhythmias that are most common include atrial fibrillation (AF), which is linked to higher rates of death and morbidity as well as potentially fatal consequences such heart failure and stroke. Consequently, this study was conducted and aimed to test the hypothesis that measurement of the total atrial conduction time PA-TDI (Time-interval from initiation of the electrocardiographic P wave recorded by the echo machine (lead II) to the peak of the A wave of the atrial tissue Doppler tracing) and speckle tracking echo enable prediction of occurrence atrial fibrillation. Methods: We included 90 patients that were subdivided into two groups, first group with no history of AF and second group with history of Paroxysmal AF. Complete conventional echocardiography parameters were performed on admission including (2D, Doppler and Tissue Doppler Image modalities that were acquired in the standard parasternal and apical views, left atrial strain, LA reservoir strain, LA contractile and A conduit strain) to test the hypothesis of PA-TDI. Results: comparison between the two study groups revealed significant variations between two groups regarding the variables of transmitral Doppler inflow. The mean± SD of peak E velocity and peak A velocity of group A were 81.60±7.81 and 55.28±8.47, respectively, whereas that of group B were 9.56±8.79 and 65.89±17.03, respectively with pvalue of 0.006 and 0.003, respectively. the mean± SD of PA-TDI duration of group A was 127.72±19.69 and it was 148.92±24.60 for group B with significant difference between the two groups. Conclusion: Speckle tracking echo and atrial tissue Doppler imaging parameters (PA-TDI) are promising tools to predict an occurrence of atrial fibrillation.
