Propafenone Overdose Presenting With Brugada Phenocopy, QRS Widening, and Ventricular Fibrillation.
Article in JACC. Case reports, 2026. 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
backgroundBrugada phenocopy (BrP) denotes reversible Brugada-type electrocardiogram changes from transient triggers, requiring management distinct from congenital Brugada syndrome. CASE SUMMARY: A 19-year-old man collapsed at home, regained consciousness in transit, and soon after emergency department arrival had recurrent syncope with ventricular fibrillation, which was defibrillated (200 J). The electrocardiogram showed PR interval approximately 200 milliseconds, QRS interval approximately 160 milliseconds, QTc interval approximately 489 milliseconds, lateral J-waves, and coved ST-segment elevation in V DISCUSSION: The triad of diffuse conduction delay, V TAKE-HOME MESSAGES: BrP resolves after correcting reversible triggers. In sodium-channel blocker toxicity with QRS interval widening, early sodium bicarbonate is first-line therapy.
