No sustained arrhythmias or adverse events occurred.Conclusions ECG changes including prolongation of the PR, QRS, and QTc intervals were seen in all children who underwent procainamide challenge for evaluation of possible Brugada syndrome. An increase in the PR, QRS, and QTc intervals of at least...

Testing provoked a Brugada pattern in 12 subjects (6.9%), 5 of whom had no ST abnormalities at baseline. No subjects with a negative procainamide challenge were subsequently diagnosed with Brugada syndrome. Genetic testing was conducted in 10 of the 12 subjects with a provoked Brugada pattern ...
Background: A type 1 Brugada electrocardiographic pattern precipitated by an SCB challenge confers a diagnosis of Brugada syndrome. Methods: Patients undergoing an SCB challenge were prospectively enrolled across Canada and the United Kingdom. Patients with no prior cardiac arrest and family histories ...
