Spontaneous ST-Segment Elevation in Right Precordial Leads Following Cardiac Arrest: Literature Review and Management Proposal for Ruling out Brugada Syndrome.
Review in Cardiovascular drugs and therapy, 2026. 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
purposeElectrocardiogram (ECG) evaluation after return of spontaneous circulation (ROSC) represents a crucial step in the diagnostic work-up of sudden cardiac death (SCD) survivors. Among ECG patterns, the Brugada syndrome (BrS) type 1 morphology, characterized by coved ST-segment elevation in right precordial leads, requires a prompt differential diagnosis, as it may reflect either a true BrS, or a BrS phenocopy, or yet an acquired sodium channel dysfunction.
methodsThis focused narrative review provides an analysis of Brugada-like ECG patterns occurring in the post-ROSC setting, summarizing the pathophysiological mechanisms, diagnostic criteria, and distinctive features of each potential etiology.
resultsBrS is an inherited arrhythmogenic disorder associated with an increased risk of ventricular arrhythmias and SCD. Conversely, Brugada phenocopies are transient Brugada-like ECG patterns triggered by reversible conditions, including ischemia, pulmonary embolism, pneumothorax, hypothermia, electrolyte and metabolic disturbances, myocardial or pericardial inflammation, or intracranial hemorrhage. A diagnostic algorithm is proposed to guide clinicians through rapid evaluation, prioritizing the exclusion of life-threatening and reversible causes before considering primary electrical disorders.
conclusionsEarly recognition and targeted management of these entities are fundamental, as prompt correction of the underlying condition often leads to complete ECG normalization, avoiding misdiagnosis. Understanding the spectrum of Brugada mimics is essential for improving diagnostic accuracy and optimizing therapeutic strategies in the acute management of post-cardiac arrest patients.
