Abstract
Background: Although the early re-polarization pattern known as a benign condition, it can result in idiopathic ventricular fibrillation and sudden cardiac death. In this study, we aimed to evaluate the prevalence of early repolarization pattern in young healthy men. Methods and Patients: Four hundred fourteen young healthy man were enrolled in the study. PR intervals, QRS durations, QT intervals and corrected QT durations were measured from electrocardiographic records. Early re-polarization pattern was defined as if an elevation J-point was greater than 0,1 mV according to the isoelectrical point. Results: The prevalence of early repolarization pattern was 23,2 % (n=96). Of these, we found early re-polarization pattern in inferior, lateral and inferolateral leads with 14,7%, 2,2% and 6,3% respectively. There was a significant relation between heart rate and elevation of J point. Conclusion: The prevalence of early repolarization pattern in young healthy men from Turkey was similar with the previously reported rates from different white populations.
Highlights
Material and MethodsEarly repolarization pattern (ER) is characterized by if elevation of J point, that is junction between the end of QRS complex and the beginning of the ST segment is greater than 0,1 mV
We found early repolarization pattern in inferior, lateral and inferolateral leads with 14,7%, 2,2% and 6,3% respectively
ER syndrome is defined as sudden cardiac death or occurrence of ventricular fibrillation (VF)/ polymorphic ventricular tachycardia (VT) that cannot be explained in patient with ER pattern [9]
Summary
Repolarization pattern (ER) is characterized by if elevation of J point, that is junction between the end of QRS complex and the beginning of the ST segment is greater than 0,1 mV. It is required at least two subsequent derivation with ERP for diagnosis [1,2]. ER syndrome is defined as sudden cardiac death or occurrence of VF/ polymorphic ventricular tachycardia (VT) that cannot be explained in patient with ER pattern [9]. Existence of strong evidence between the sudden cardiac death and ER pattern and due to absent of literature knowledge about ER pattern of young men in Turkey, we aimed to find the rate of ER pattern among young healthy men in Turkey
