The effect of age and gender on the electrocardiogram in children

Area of Science:

• Pediatrics
• Cardiology
• Biomedical Engineering

Background:

• Establishing normative data for electrocardiographic (ECG) parameters is crucial for pediatric cardiology.
• Previous studies may not adequately represent diverse pediatric populations or account for developmental changes.
• Understanding age and gender-specific ECG variations aids in accurate diagnosis and monitoring of pediatric cardiac health.

Purpose of the Study:

• To determine the influence of age and gender on electrocardiographic measurements in a large cohort of Turkish children.
• To establish age- and gender-specific normal limits for key ECG parameters.
• To compare findings with existing pediatric ECG reference values.

Main Methods:

• Analysis of standard 12-lead electrocardiograms from 2241 healthy Turkish children (1 day to 16 years).
• Utilized a computer program for precise measurement and analysis of ECG parameters.
• Data stratified into 12 age groups to identify developmental trends.

Main Results:

• Clinically significant age-dependent differences in ECG measurements were observed across 12 pediatric age groups.
• Gender-specific variations in ECG amplitude and duration were identified, particularly pronounced in adolescents.
• New reference ranges for ECG parameters were generated, reflecting Turkish pediatric population characteristics.

Conclusions:

• Age and gender are critical factors influencing normal electrocardiographic values in children.
• The established age- and gender-specific normal limits provide a valuable resource for pediatricians and cardiologists.
• This study contributes essential normative data for the accurate interpretation of pediatric ECGs in the Turkish population.
