Abstract
Background: Sudden cardiac death (SCD) in young adults has a rare incidence but it is tragic .It affect five per 100,000 yearly according to some studies. One of the main causes of SCD especially in young adults is nonstructural heart diseases that include long QT syndrome, short QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, idiopathic ventricular fibrillation (IVF), atrio-ventricular node block, and recently early repolarization. In Egypt there is no sufficient data about prevalence of these diseases or normal ECG parameters. The aim of this work is to assess the mean and standard deviation of electrocardiography (ECG) parameters in healthy Zagazig University students which will help in addition to old studies and coming studies to better management of sudden cardiac death especially in young adults.
Methods: In this study we collected a random sample of healthy students from Zagazig University Student Hospital (during general examination during the application for the university) and student accommodation in August and September 2017.Our sample size was 800 students ,474 were females and 326 were males ,the mean age was 18.42 ± 1.1.
Results: Athletes has a slower heart rate, wider QRS , and longer QT interval than non-athletes. Females have longer QT and narrower QRS than males.
Conclusion: there is a significant difference between athlete and non-athlete and also there is a significant difference between male and female in the mean and standard deviation of QT interval, QRS duration, and heart rate.
