Frequent premature ventricular contractions induced by fluconazole: A case report.
Article in IDCases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Introduction: Fluconazole is commonly used to treat and prevent fungal infections caused by Candida and Cryptococcus species. Although there have been reports of fatal arrhythmias induced by fluconazole, such as torsades de pointes, there have been minimal reports of mild, non-fatal arrhythmias associated with it, which may have been overlooked in clinical practice. We encountered a case of frequent premature ventricular contractions induced by fluconazole during the treatment of HIV-related pulmonary cryptococcosis. Herein, we report a case of frequent premature ventricular contractions (PVCs) induced by fluconazole, along with a literature review. Case presentation: A 47-year-old man diagnosed with human immunodeficiency virus-related pulmonary cryptococcosis experienced an irregular heartbeat during antifungal therapy with fluconazole at 400 mg once daily. A 12-lead electrocardiogram was conducted, which displayed frequent unifocal PVCs originating in the right ventricular outflow tract without QT prolongation. After reducing the dose of fluconazole to 200 mg once daily, the patient's symptoms slightly improved, and PVC frequency decreased on a 12-lead ECG; however, PVCs did not disappear. After discontinuing fluconazole, the symptoms improved, and a follow-up 12-lead electrocardiogram showed no PVCs. Conclusions: We encountered the case of frequent PVCs induced by fluconazole during the treatment of human immunodeficiency virus-related pulmonary cryptococcosis. Furthermore, it was suggested that the PVC frequency was dose-dependent for fluconazole. Careful follow-up for new-onset arrhythmias and ECG evaluations are essential before and after fluconazole administration.
