Wide QRS Complex Tachycardia in a Patient With Acute Myocarditis Temporarily Protected With a Wearable Cardioverter-Defibrillator.
Article in Cureus, 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
A wearable cardioverter-defibrillator (WCD) provides noninvasive and temporary protection against sudden cardiac death (SCD) in patients at transient risk of ventricular arrhythmias, including myocarditis. We report the case of a 68-year-old man with recurrent wide QRS complex tachycardia (WCT) and myocarditis confirmed by cardiac magnetic resonance imaging, who was discharged with a WCD following in-hospital stabilization. During the one-month follow-up, the device detected 200 WCT episodes, lasting up to 50 seconds and reaching rates of 150 beats per minute, despite clinical improvement and recovery of left ventricular ejection fraction (from 47% to 52%). An electrophysiological study revealed orthodromic atrioventricular reentrant tachycardia mediated by a retrogradely conducting accessory pathway (AP), reproducing the WCT morphology recorded by the WCD. Radiofrequency ablation of AP successfully eliminated the arrhythmia. This case highlights the diagnostic value of prolonged electrocardiographic monitoring with WCD beyond protection from malignant arrhythmia, enabling timely intervention and avoidance of unnecessary implantable cardioverter-defibrillator implantation.
