Abstract
PURPOSE: We report a case of a patient experiencing paroxysmal supraventricular tachycardia after infusing doxophylline. METHODS: Clinical evaluations and the electrocardiogram were performed by specialists. FINDINGS: Our patient felt palpitations and chest distress after intravenous Doxophylline. The electrocardiogram showed paroxysmal supraventricular tachycardia. There was no evidence to prove that there was any problem with his heart, liver, and kidney. According to the Naranjo Adverse Drug Reaction probability scale, paroxysmal supraventricular tachycardia has a probable relationship with Doxophylline. IMPLICATIONS: The paroxysmal supraventricular tachycardia is a rare but reasonable adverse reaction of Doxophylline, which should be paid more attention.
