1 · What the graph read from it

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.

2 · The registry

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

Wide complex tachycardia (WCT) presents a diagnostic challenge, particularly in distinguishing ventricular tachycardia (VT) from supraventricular tachycardia (SVT) with aberrancy. We report an 81-year-old man with recurrent WCT initially suspected to be VT based on clinical and electrocardiographic features. However, inconsistencies across serial electrocardiographic tracings limited diagnostic certainty. Specifically, variations in polarity across all limb leads, except aVR and the precordial leads, raised suspicion for limb lead misplacement, particularly left arm-left leg reversal. This electrocardiographic perplexity further complicated the clinical interpretation. To clarify the underlying arrhythmia mechanism, an electrophysiology (EP) study was performed, which demonstrated inducible tachycardia with simultaneous atrioventricular activation (VA = 0), consistent with typical atrioventricular nodal reentrant tachycardia (AVNRT) with aberrancy. Successful slow pathway ablation rendered the arrhythmia noninducible, and the patient has remained free of recurrent arrhythmia during five months of follow-up. This case highlights the limitations of ECG-based algorithms and the importance of careful ECG interpretation and invasive evaluation.
