Persistent Supraventricular Tachycardia Following Central Venous Catheter Insertion: When Withdrawal of the Mechanical Stimulus Is Not Enough.
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
Cardiac arrhythmias are a recognised complication of central venous catheterisation and are usually attributed to mechanical irritation of the endocardium by the guidewire or catheter tip. These arrhythmias typically resolve following withdrawal of the mechanical stimulus. We report a 42-year-old man with heart failure with reduced ejection fraction and diabetic ketoacidosis who developed an abrupt regular narrow-complex tachycardia at approximately 217 beats/min immediately following advancement of a right internal jugular central venous catheter. The arrhythmia was associated with transient hypotension and dizziness and persisted despite removal of both the guidewire and catheter. This case illustrates that catheter manipulation may trigger a sustained supraventricular tachycardia that persists after removal of the mechanical stimulus, particularly in a patient with structural heart disease and metabolic and electrolyte abnormalities. Persistent tachyarrhythmia following catheter withdrawal should prompt assessment of haemodynamic stability and guideline-directed arrhythmia management rather than an assumption of spontaneous resolution.
