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.
心电图中相邻导联持续出现1毫米或更高的J点抬高被认为是早期复极所致。这种情况过去被认为是良性的，但目前被认为是特发性室颤和猝死的罕见原因。目的：本研究的主要目的是找出加德满都医学院教学医院接受心电图检查的受试者中早期复极模式的患病率。方法：对加德满都医学院教学医院就诊患者的12导联心电图进行研究。收集患者详细信息的数据。对心电图进行早期复极类型分析。结果：心电图早期复极模式的总体患病率为2.82%。其在男性和女性中的患病率分别为4.95%和0.77%。在研究人群中，I型、II型和III型早期复极模式的不同类型早期复极心电图模式的患病率分别为0.70%、1.25%和0.63%。在我们的研究中未检测到IV型或Brugada模式。结论：观察到的最常见模式是II型，即下壁或下侧壁导联的早期复极模式。了解早期复极及其类型有助于向医生提供有关心律失常和心源性猝死风险的咨询。
