Objective: The early repolarization is the abnormality identified as elevation of junction between QRS complex and the ST segment in 2 consecutive leads on the electrocardiogram. Early repolarization frequency differed greatly between populations. But no evidence exists in the literature regarding the extentermine the frequency of earlthe Pakistaniization on electrocardiography in non-cardiac individuals. of early repolarization in Pakistani general population. Therefore, we planned this study. To determine the frequency of early repolarization on electrocardiography in non-cardiac individuals.

Method: Cross-Sectional Study, Punjab Institute of Cardiology , Lahore,  About 6 months, i.e., 01st July 2023 to 31st December 2023. Non-cardiac individuals of age 25-65 years, both genders, were included in the study and underwent electrocardiography. Findings were recorded; early repolarization was noted. All this information was recorded in pro forma while analyzed in SPSS version 25. Early repolarization was presented as frequency and percentage.

Results: The mean age of individuals was 42.31 ± 12.58 years. There were 73 (69.5%) male individuals while 32 (30.5%) female individuals. Out of 105 individuals, 8 (7.6%) had early repolarization on electrocardiography while 97 (92.4%) individuals did not had early repolarization on electrocardiography.

Practical Implication:  Early repolarization on electrocardiography (ECG) is uncommon in this population, with only 7.6% of individuals exhibiting this pattern. Clinicians should be aware of this, as it may not be a routine finding in similar populations, aiding in informed decision-making about cardiac evaluation or management.

Conclusion: It has been concluded that frequency of early repolarization is very low in non-cardiac individuals.
