Adenosine is primarily used in Advanced Cardiovascular Life Support (ACLS) to convert certain types of supraventricular tachycardia (SVT) to normal sinus rhythm. Supraventricular tachycardias are rapid heart rhythms originating above the ventricles, and they can significantly compromise hemodynamic stability. Adenosine works by temporarily blocking conduction through the atrioventricular (AV) node, which can interrupt reentrant circuits common in SVT. This interruption often restores normal sinus rhythm effectively within a few seconds after administration, making it a critical drug in managing these arrhythmias in acute situations.

The use of adenosine is specific and precise, as it is not indicated for increasing heart rate, treating hypotension, or simply stabilizing the heart rate in a general sense. Instead, its action is focused on providing a rapid and effective solution for terminating certain tachyarrhythmias.
