Anesthesia with Propofol Effects on Atrial Fibrillation Wavefront Delays

摘要: Since the cardiac activity during atrial fibrillation (AF) may be influenced by autonomic modulations. In this study a new method to quantify effect of most useful anaesthetic agent (propofol) on patterns will introduced. This is based in measurement delay between two activations. Experimental data were obtained using bipolar catheter atria 27 patients AF. The single averaged index from adjacent pairs recordings situated left and right areas was computed. results showed that has different behaviour both infusion, what congruence with previous corroborate it as valid descriptors electrophysiological properties tissues.
