Radiofrequency catheter ablation for drug-refractory atrial tachyarrhythmias in a patient with catecholaminergic polymorphic ventricular tachycardia: A case report.
Article in Journal of cardiology cases, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Patients with catecholaminergic polymorphic ventricular tachycardia (CPVT) frequently have atrial arrhythmias, such as atrial tachycardia (AT) and fibrillation (AF), in addition to the ventricular tachyarrhythmias. The development of AT/AF in patients with CPVT is associated with adverse outcomes, and its management is still challenging. A 43-year-old woman with CPVT underwent radiofrequency catheter ablation (RFCA) for drug-refractory AT/AF. Pulmonary vein isolation (PVI) was carried out prior to AT ablation. Repetitive rapid firing from the left superior PV occurred frequently during PVI. After completion of PVI, the firing disappeared, but both polymorphic VT and multifocal ATs were induced by infusion of isoproterenol (ISP) (0.5 mcg/min). The origins of the two ATs were in the right atrium (RA) posterior septum [cycle length (CL), 285 ms] and ostium of the coronary sinus (CS) (CL, 235 ms). Electrophysiologic evaluation revealed that the earliest activation occurred at the RA posterior septum and CS ostium, preceding the onset of P waves by 52 ms and 84 ms, respectively. Application of radiofrequency energy at the site terminated ATs. After RFCA of the two ATs and PVI, no atrial tachyarrhythmias were induced by continuous ISP administration (0.5 mcg/min). <
