Medications
-
Electrophysiologic mechanism of atrioventricular nodal reentry tachycardia (AVNRT).
-
Atypical atrioventricular nodal (AV) reentry tachycardia. Often, an inverted P wave is seen just before the QRS complex in leads II, III, aVF. This represents activation of the posterior septum due to antegrade conduction via the fast pathway and retrograde conduction via the slow pathway of the AV node.
-
Typical atrioventricular nodal (AV) reentry tachycardia. In this electrocardiogram, the P wave appears immediately after or just within the QRS complex. Often a “pseudo R wave" is seen in lead V1 and a “pseudo S wave" in leads II, III, aVF. The retrograde P wave represents retrograde activation via the fast pathway, which is anterior septal and superior to the AV node.
