Gender differences in the electrocardiogram screening of athletes

Area of Science:

• Cardiology
• Sports Medicine
• Medical Screening

Background:

• Electrocardiograms (ECGs) exhibit gender-related variations.
• Cardiovascular screening protocols for athletes often overlook these differences.
• Understanding gender-specific ECG parameters is crucial for accurate interpretation in young athletes.

Purpose of the Study:

• To evaluate gender differences in electrocardiogram (ECG) parameters among young athletes.
• To discuss the implications of these gender-specific ECG findings for cardiovascular screening.
• To assess the applicability of the Seattle ECG criteria in young athletes of different genders.

Main Methods:

• An observational, cross-sectional study was conducted.
• ECGs from 1436 student athletes (2013-2014) were analyzed using computer-based measurements.
• The Seattle ECG criteria were applied to assess cardiac findings.

Main Results:

• Male athletes showed significantly higher PR intervals and QRS duration.
• Female athletes exhibited higher resting heart rates and QTc intervals.
• Specific ECG findings like sinus bradycardia and early repolarization were more prevalent in males.

Conclusions:

• Significant gender-related differences exist in the ECGs of young athletes.
• These ECG variations should be considered in cardiovascular screening protocols.
• Further research is recommended on gender-based cutoff values for QRS duration in the Seattle ECG criteria.
