The world of cardiac electrophysiology can be daunting, so we suggest that you listen to this insightful conversation with the experts. Deputy Editor Dr. Zamaneh Kassiri (University of Alberta) interviews authors Dr. Crystal Ripplinger (University of California Davis), Dr. Nikki Posnack (The George Washington University and Children's National Hospital), Dr. Alexey Glukhov (University of Wisconsin-Madison), Dr. Matthew Kay (The George Washington University), Dr. Carol Ann Remme (Amsterdam University Medical Centers), and Dr. Alex Quinn (Dalhousie University) about their comprehensive new guidelines for assessment of cardiac electrophysiology and arrhythmias in small animals. This thorough guidelines article by Ripplinger et al. covers many common electrophysiology approaches used in the field at the tissue level, whole heart level, and in vivo measurements. In addition, the authors dive into what parameters investigators may want to measure, providing helpful and clear guidance on how to calculate such parameters and what those parameters might mean in terms of electrophysiology remodeling and arrhythmia propensity. Both senior investigators and trainees will find these guidelines approachable and useful. Listen and learn from the experts.
