Left lateral pathway AVRT causing overdrive suppression of SA node and reversible cardiomyopathy: A case report.
Article in Indian pacing and electrophysiology journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
The SA node is protected from the overdrive suppression by the other tissues or tachyarrhythmias by means of atrio-sinus entrance block. A 57-year-old woman presented with symptomatic tachy-brady syndrome and severe LV dysfunction. Electrophysiological study revealed presence of left lateral accessory pathway. After ablation of the accessory pathway, tachycardia could no longer be induced. Her LV systolic function significantly improved on follow up and an external loop recorder showed no episodes of bradycardia. Therefore, we conclude that the bradycardia was due to overdrive suppression of SA node caused by AVRT, and the reversible cardiomyopathy was also due to high tachycardia burden.
