case_images: (A) Supraventricular tachycardia at admission; (B) Torsades des pointes after adenosine infusion. "Adenosine" handwritten on the electrocardiograph strip tracing is the Brazilian Portuguese word for adenosine; (C) Post-cardioversion electrocardiogram showing aVR ST elevation and diffuse ST depression; (D) Electrocardiogram 6 hours after admission

case_images: Electrocardiography on admission revealed supraventricular tachycardia (Figure 1A). The rhythm degenerated to non-sustained polymorphic ventricular tachycardia (Figure 1B) and spontaneously reverted to sinus rhythm in less than 30 seconds. The second electrocardiogram showed ST-segment elevation in lead aVR and ST-segment depression in the inferior and anterolateral leads (Figure 1C). The patient recovered completely and spontaneously within a few minutes, with electrocardiogram normalization (Figure 1D).
