Torsade de pointes during an oral surgery caused by a combination of herbal medicine-induced pseudoaldosteronism and trigeminocardiac reflex.

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
Licorice can cause pseudoaldosteronism and QT prolongation as its side effect. Trigeminal nerve stimulation, including surgical intervention involving the face, can cause transient bradycardia, known as the trigeminocardiac reflex. Although rare, a combination of these two etiologies can cause ventricular tachycardia. A 50-year-old female patient with a history of hypertension and intake of an herbal drug containing licorice underwent impacted wisdom tooth extraction under general anesthesia. Immediately after placing a month-long prop for visualization in the oral cavity, sinus bradycardia occurred, followed by ventricular tachycardia and torsade de pointes. Mouth prop was removed and cardiopulmonary resuscitation was initiated, and the arrhythmia was resolved. Hypokalemia, metabolic alkalosis and normal aldosterone levels were observed. An inverted T wave and a prominent U-wave were observed on the electrocardiogram. Potassium excretion in urine was normal, although hypokalemia was present. The patient was treated with potassium correction.
