Özet
Objective: It has been reported that early repolarization (ER) abnormalities, which have been considered benign for many years, may be associated with many cardiac arrhythmias both malign and benign in the recent period. In our study, we investigated that may be coexisting the atrioventricular nodal reentrant tachycardia (AVNRT), which the most common in paroxysmal tachycardias, with ER abnormalities. Methods: Our study was designed as a single-centered retrospective descriptive study. The study enrolled 53 patients who underwent ablation due to AVNRT and 50 control group patients. Demographic, clinical, and laboratory data of patients were retrieved from our database. ER, the diagnosis and types of the pattern were determined based on the consensus report published by in 2015. Electrocardiographic measurements were performed semi-automatically by EP caliper application. Results: Of the patients enrolled in the study, 34 (64.2%) in the AVNRT group and 31 (62%) in the control group were female. The mean age was 47.11±12.79 years in the AVNRT group and the mean age was 44.88±13.02 years in the control group. Although the presence of an ER pattern was numerically higher in the AVNRT group compared with the control group, this difference was not statistically significant. A comparison was made between subgroups, and the slurring with ST elevation type of ER pattern was significantly higher in men [7 people (58.3%) in males 0 in female, p<0.001], the slurring without the ST elevation type of ER pattern was significantly higher [15 people (93.8%) in females and 5 people (41.7%) in males, p<0.002]. Conclusion: In our study, we determined that the pattern of early repolarization, especially the slurring type, was more frequent in patients with AVNRT; however, but this difference was not statistically significant. Additionally, we found that the slurring with ST elevation type of ER is significantly more common in males, whereas the slurring without the ST elevation type of ER is significantly more common in females.
