Third-degree atrioventricular block induced by escitalopram and quetiapine in a patient with depression: a case report.
Article in American journal of translational research, 2025. 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
Third-degree atrioventricular block (AVB) associated with the use of escitalopram and quetiapine is rare, with limited cases reported. We present a case of drug-induced third-degree AVB in an elderly patient undergoing treatment for depression. A 70-year-old woman with a history of depression was initially treated with milnacipran and alprazolam, but the regimen was altered due to insufficient therapeutic response. Two weeks after initiating escitalopram and quetiapine, she developed third-degree AVB. Electrocardiogram (ECG) revealed sinus rhythm with complete AV block, atrioventricular junctional escape rhythm, QT interval prolongation, and a heart rate of 45 bpm. Emergency pacemaker implantation was performed. This case highlights the potential for escitalopram and quetiapine to induce serious cardiac conduction abnormalities, particularly in elderly patients. Regular ECG monitoring is essential when prescribing these agents to minimize the risk of malignant arrhythmia.
