Abstract :Background: The interatrial block is a condition that occurs due to the delay of conduction in the right atrium to the left atrium, and can be partial insert ignore into journalissuearticles values(pIAB); or advanced insert ignore into journalissuearticles values(aIAB);, and also is associated with atrial arrhythmia. Diastolic dysfunction insert ignore into journalissuearticles values(DD); is an important condition frequently encountered in most healthy middle-aged individuals and plays a role in the development of many cardiovascular diseases. It is noteworthy that frequent paroxysmal AF insert ignore into journalissuearticles values(PAF); attacks are observed especially in individuals with DD in clinical life, and its relationship with the presence of interatrial block is still unclear in these patients. Our aim in this study was to evaluate the relationship between the presence of DD and the development of interatrial block and PAF. Methods: A total of 146; 92 patients with DD and 54 control insert ignore into journalissuearticles values(proven by echocardiography); were enrolled in this cross-sectional and prospectively study. The properties of the P wave were evaluated in leads D2-3 aVF and V1. Echocardiography and electrocardiography results of the two groups were compared. Results: The mean age of the DD and the control group was insert ignore into journalissuearticles values(62.3 ± 0.74 and 61.2 ± 0.61 years, p=0.481); respectively. The frequency of IAB was significantly higher in the DD than the control group insert ignore into journalissuearticles values(%37-%46.7-%16.3, %77.8-%18.5-%3.7, none-pİAB-aİAB, respectively);. In the correlation analysis, there was a strong correlation between the presence of DD and IAB insert ignore into journalissuearticles values(r: 0.439, p <0.001);, and the history of PAF and IAB insert ignore into journalissuearticles values(r: 0.458, p <0.001);. Conclusion: In our study, the frequency of IAB was significantly higher in the DD group. We think that it may be beneficial to evaluate P waves more carefully to determine the risky individuals among those who have DD in clinical life.
