HRS Board Review 2025 New Courses (Reviewers Copy)-Workshop 1_Tomaselli_2025

Video Transcription

Hello, my name is Gordon Tomaselli and we'll be in workshop one here talking about some  of the fundamental features of cardiac electrophysiology in this particular workshop. I'm from the  Albert Einstein College of Medicine. So let's jump right in. First, I have no significant disclosures. I have NIH grants and I am on the scientific advisory board of the LeDuc  Foundation. So question one, action potentials are elicited from ventricular myocytes at different pacing intervals shown in panels A and B. Which best explains the difference  between the action potentials in panels A and B? Cells in panel A have been exposed to rinolazine. Cells in panel A have been exposed to diltiazem. Cells in panel A have  been exposed to dofetilide. Or cells in panel A have been exposed to amiodarone. I'll give you a couple minutes to consider this.

Video Summary

Dr. Gordon Tomaselli, from the Albert Einstein College of Medicine, leads a workshop on cardiac electrophysiology, focusing on action potentials in ventricular myocytes. He mentions having no significant financial disclosures but holds NIH grants and is part of the LeDuc Foundation's scientific advisory board. The workshop presents a comparison of action potentials elicited at various pacing intervals. Participants are asked to determine which drug exposure explains the differences between two panels of action potentials: rinolazine, diltiazem, dofetilide, or amiodarone.
