Adenosine administration for supraventricular tachycardia can rarely cause coronary spasm presenting with ST segment elevation.
Alerts clinicians to rare adenosine-induced coronary spasm in SVT; leaves incidence and risk factors open.
Adenosine is commonly used as a pharmacological agent in myocardial perfusion imaging, as an antiarrhythmic agent, and in Cath Lab. during PCI for treating no reflow phenomenon. Coronary spasm has been reported following adenosine injection during stress imaging. We report a rare complication with ST segment elevation, following adenosine injection, given for treatment of supraventricular tachycardia.
