Key result
Original exercise stress protocol meets termination criteria in 100% of children versus standard Bruce protocol.
Why the study?
To develop a protocol for diagnosing exercise-induced arrhythmias and conduction disturbances in children aged 3-6 years without structural heart disease.
Does an original exercise stress testing protocol improve the achievement of termination criteria compared to the standard Bruce protocol in children aged 3-6 years with arrhythmias?
Population
20 children aged 58,7±2,12 months with ventricular arrhythmias and/or AV block without structural heart disease
Comparison
Exercise stress testing using original vs Bruce protocols

May improve exercise testing success in preschool children with arrhythmias; hypothesis-generating and requires prospective validation.
Cross-Sectional (n=20)
Does an original exercise stress testing protocol improve the achievement of termination criteria compared to the standard Bruce protocol in children aged 3-6 years with arrhythmias?
Odds Ratio: 116 (95% CI 5.93–2250)
Absolute Event Rate: 100% vs 25%
p-value: p=0.0017
An original exercise stress testing protocol significantly increases the achievement of termination criteria and diagnostic yield for arrhythmias in preschool children compared to the standard Bruce protocol.
Васичкина et al. (2022) conducted a cross-sectional in Ventricular arrhythmias and/or atrioventricular block (n=20). Original exercise stress testing protocol vs. Standard Bruce protocol was evaluated on Achievement of the termination criteria (OR 116, 95% CI 5.93-2250, p=0.0017). An original exercise stress testing protocol achieved termination criteria in 100% of children compared to 25.0% with the standard Bruce protocol (OR 116; 95% CI 5.93-2250; p=0.0017).
