Key Result

Adenosine administration for supraventricular tachycardia rarely induces ST-segment elevation with chest pain, suggesting transient myocardial ischemia or coronary vasospasm.

Key Points

To investigate the rare occurrence of ST-segment elevation after adenosine administration for SVT.
Analyzed ECG changes during adenosine administration.
Monitored symptoms such as chest pain, flushing, and hypotension.
Reviewed cases reporting ST-segment elevation following treatment.
ST-segment elevation was observed in a subset of patients receiving adenosine.
Symptoms of chest pain accompanied ST-segment elevation in some cases.
Incidence of flushing and hypotension was reported, emphasizing monitoring during treatment.

Structured PICO

Population

Patients with paroxysmal supraventricular tachycardia

Intervention

Adenosine

Outcome

ST-segment elevation with chest painsafety

Careful ECG monitoring is needed during adenosine administration for SVT due to the rare risk of ST-segment elevation and chest pain.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

ABSTRACT Adenosine, used to treat paroxysmal supraventricular tachycardia, commonly causes flushing, sweating, palpitations, and hypotension. Rarely, it may induce ST‐segment elevation with chest pain, suggesting transient myocardial ischemia or coronary vasospasm, highlighting the need for careful ECG monitoring during administration.
