Atrial pacing to suppress ventricular arrhythmias in the critically ill patients: a case report.
Article in European heart journal. Case reports, 2022. 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
Background: Atrial and ventricular arrhythmias are common in the critically ill due to a variety of factors including sepsis, myocardial ischaemia, renal dysfunction, and electrolyte disturbances. Anti-arrhythmic medications can be useful to control arrhythmias but can result in bradycardia and haemodynamic compromise. A paced atrial rhythm alongside normal atrioventricular conduction can be helpful to treat bradycardia, prevent arrhythmias, and support cardiac output. Case summary: A 55-year-old gentleman with pseudomonas pneumonia, respiratory failure necessitating mechanical haemodynamic support, and subsequent coronary ischaemia presented to the intensive care unit. Paroxysms of atrial fibrillation and ventricular arrhythmias caused haemodynamic embarrassment and presented an ongoing clinical challenge as anti-arrhythmic medications resulted in bradycardia and Torsade de Pointes. Atrial pacing mediated intrinsic conduction via the His-Purkinje system inhibited ventricular ectopy and further arrhythmia breaking the tachycardia-bradycardia cycle; this stabilized the patient, facilitated ongoing intensive therapy unit care and promoted recovery. Conclusion: Atrial pacing mediated intrinsic conduction via the His-Purkinje system is an effective approach to suppress ventricular ectopy and sustained arrhythmias whilst protecting the patient from haemodynamically compromising bradycardia.
