Background: Sudden cardiac death (SCD) represents a significant health concern among young athletes and military personnel. This study aimed to identify key risk factors and develop effective prevention strategies for SCD in these populations.

Methods: We conducted a comparative analysis of 156 athletes and 100 military personnel aged 13-35 years, with 50 healthy individuals as controls. All participants underwent comprehensive electrocardiographic (ECG) and echocardiographic (ECHO) evaluation.

Results: Significant differences were observed in left ventricular mass (175.6±4.62g vs 121.4±5.89g, p<0.0001), QRS complex duration (0.116±0.01 sec), and repolarization abnormalities (T-wave inversion in 7% of athletes). ECG abnormalities were prevalent in 53% of athletes and 45% of military personnel.

Conclusion: Regular cardiac screening with ECG and ECHO demonstrates high sensitivity (92%) for early detection of SCD risk factors. Implementation of personalized training regimens and continuous monitoring is recommended for high-risk individuals.
