Accelerated idioventricular rhythm observed under total intravenous anesthesia using remifentanil propofol and rocuronium

摘要

Accelerated idioventricular rhythm (AIVR) during anesthesia has been described in several drug toxicity such as from cocaine, halothane, desflurane, and propofol. We present the case of a man who developed episodes of AIVR observed under total intravenous anesthesia (TIVA) using remifentanil, propofol, and rocuronium. AIVR during anesthesia was a benign phenomenon, and further examinations after surgery showed no structural heart disease and the daily occurrence of idioventricular arrhythmias. This case suggests that the suppression of sinus and atrioventricular nodal function and the autonomic imbalance caused by propofol and remifentanil may induce AIVR with greater frequency.
