AbstractBackground: Sudden cardiac death in the young adults is rare but it is tragic .It affects five per 100,000 yearly according to some studies. Nonstructural heart diseases that cause sudden cardiac death include long QT syndrome, short QT syndrome, Brugada syndrome , catecholaminergic polymorphic ventricular tachycardia ,idiopathic ventricular fibrillation (IVF) , AV node block , preexitation syndrome, and recently Early repolarization .Fortunately some these nonstructural heart diseases can detected by resting ECG. 
Methods: In this study we collected a random sample of students from Zagazig University Student Hospital (during general examination during the application for the university) and university student accommodation in August and September 2017.Our sample collected was 2000 students ,800 met the inclusion criteria 474 were females and 326 were males ,the mean age was 18.42 ± 1.1.
Results: Males have significant more prevalence of early repolarization, LVH, RAD, LAD, wide QRS and sinus bradycardia than females. Female have significant more prevalence of short PR, low voltage and sinus tachycardia. Athletes have significant more prevalence of early repolarization, RAD, wide QRS, LVH, sinus bradycardia and long QT than non-athletes.
Conclusion: There is a variation in prevalence of ECG abnormalities between males and females, athletes and non-athletes like in early repolarization, LVH, RAD, LAD, wide QRS, sinus bradycardia, sinus tachycardia, long QT, short PR, WPW and low voltage.
