Prolongation of AV nodal conduction: case report A 75-year-old man developed prolongation of atrioventricular (AV) nodal conduction while receiving amiodarone for ventricular tachycardia (VT). The man was admitted VT storm. He received shock therapy. He started receiving IV amiodarone [dosage not stated]. However, he developed prolongation of his AV nodal conduction to 300ms at a base rate of 90beats/min. The paced atrioventricular delay (AVD) was programmed at 350ms to allow for appropriate paced AVD search with a 50ms offset subsequently applied. He developed VT at a rate of 163bpm with a cycle length of 367ms, and he was found unresponsive. He underwent direct current cardioversion an his sinus rhythm restored. Tan WA, et al.
