A case of Hyperkalemia-induced Brugada Phenocopy: a rare but serious electrocardiographic imposter.
Article in Oxford medical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Brugada Syndrome is a potentially fatal, hereditary cardiac disorder that may precipitate sudden cardiac death if not identified. An electrocardiogram (ECG) revealing a characteristic coved ST segment elevation followed by negative T wave in a right-sided precordial lead is pathognomonic for the Brugada pattern. Recently it has been shown that certain abnormalities, such as an electrolyte disturbance, may precipitate a Brugada pattern on ECG. Once the precipitating factor is treated, the rhythm reverts to baseline, coining the term Brugada Phenocopy. Here we present a captivating case of a 40-year-old female who was found unresponsive and determined to have a Brugada pattern on ECG secondary to hyperkalemia. Once appropriately treated, ECG reverts to normal baseline.
