Abstract
ST-segment elevation in patients sedated with propofol may be a sign of imminent malignant arrhythmias. Although propofol infusion syndrome-electrocardiographic abnormalities are usually described as Brugada-pattern, in unique cases nearly ubiquitous and extensive J-point and ST-segment elevation may be observed. These patients should undergo an ajmaline test following recovery. (Level of Difficulty: Beginner.).
