Vagal maneuvers can terminate certain supraventricular tachycardias by boosting parasympathetic tone and slowing conduction through the AV node. When a patient presents with a rapid, irregular or regular rhythm on ECG but remains hemodynamically stable, a noninvasive move like bearing down (the Valsalva maneuver) can interrupt reentrant circuits that cause SVT and restore normal rhythm. In this scenario, the patient is alert, with a reasonable blood pressure and no signs of shock, making a simple, noninvasive intervention the best first step. If bearing down fails, subsequent options would include medications such as adenosine (with proper monitoring) or, if the patient deteriorates, synchronized cardioversion. Defibrillation is reserved for pulseless VT/VF or other unstable rhythms, and charcoal is not relevant to a caffeine-triggered rhythm issue. Checking glucose might be part of a broad assessment, but it does not address the arrhythmia itself.
