Abstract
ABSTRACT
Background
The finding of persistent Junction point elevation of 1 mm or more in adjacent leads
in electrocardiogram is considered to be due to early repolarization. This condition
was considered benign in the past but presently it is believed to be the rare cause of
idiopathic ventricular fibrillation and sudden death.
Objective
The main objective of the study is to find out the prevalence of early repolarization
pattern in subjects having electrocardiogram at Kathmandu Medical College Teaching
Hospital.
Method
Twelve lead electrocardiograms of patients attending Kathmandu Medical College
Teaching Hospital were studied. Data was collected for patient particulars.
Electrocardiograms were analyzed for the type of early repolarization.
Result
The overall prevalence of early repolarization pattern of electrocardiogram was
2.82 %. It’s prevalence in male and female was 4.95 % and 0.77 % respectively. The
prevalence of different types of early repolarization electrocardiography pattern
was 0.70 %, 1.25% and 0.63% of the population studied for type I, II, and III early
repolarization patterns. Type IV or Brugada pattern was not detected in our study.
Conclusion
The commonest pattern observed was type II that is early repolarization pattern in
inferior or inferolateral leads. Having knowledge of early repolarization and its type
helps to counsel the physicians about the risk of arrhythmia and sudden cardiac
death.
