How is AIVR treated?
Under these situations, atropine can be used to increase the underlying sinus rate to inhibit AIVR. Other treatments for AIVR, which include isoproterenol, verapamil, antiarrhythmic drugs such as lidocaine and amiodarone, and atrial overdriving pacing are only occasionally used today.
What is AIVR rhythm?
AIVR is currently defined as an enhanced ectopic ventricular rhythm with at least 3 consecutive ventricular beats, which is faster than normal intrinsic ventricular escape rhythm (≤40 bpm), but slower than ventricular tachycardia (at least 100-120 bpm).
