Brugada Phenocopy in a Child With Parvovirus B19 Myocarditis.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSodium channelopathies predispose to life-threatening arrhythmias. Brugada phenocopies (BrPs) are nongenetic conditions that mimic Brugada syndrome and may have a reversible cause. CASE PRESENTATION: A 16-month-old child presented with a 12-day ventricular tachycardia storm and a spontaneous type 1 Brugada electrocardiogram pattern during sinus rhythm. The patient initially presented with no fever and normal ventricular function on admission that deteriorated severely within 6 days. Blood viral polymerase chain reaction was positive for parvovirus B19, and endomyocardial biopsy confirmed myocarditis. Targeted treatment led to full recovery. DISCUSSION: This is the first reported case to our knowledge of BrP caused by viral myocarditis. It highlights the diagnostic challenges and the importance of correct diagnosis and treatment. TAKE-HOME MESSAGES: In pediatric refractory ventricular tachycardia, even with a Brugada pattern (possible BrP), myocarditis should be considered, as early diagnosis and treatment can be lifesaving. Blood viral polymerase chain reaction is a highly sensitive diagnostic tool for diagnosis of viral myocarditis in children.
