Presenting on "Ablation and Defibrillation of Cardiac Tissue Using Nanosecond Pulsed Electric Fields"

Christian Zemlin, PhD, director, cardiothoracic surgery research laboratory, associate professor of surgery at Washington University School of Medicine in St. Louis, will speak at 10:00 CST on Thursday, March, 24, 2022 in Whitaker 218.

Abstract: Ablation and defibrillation are important treatment approaches to cardiac arrhythmias.   High-intensity, nanosecond pulsed electric fields can ablate cardiac tissue by electroporating the cell membranes. In a preclinical swine model, we show that nanosecond ablation has far better penetration, better speed, and less side effects than current thermal ablation methods.   Nanosecond pulses can also be used to defibrillate cardiac tissue at lower energies than conventional millisecond defibrillation.

Host: Dr.’s Chao Zhou and Jianmin Cui, Washington University in St. Louis

Speaker Information

Dr. Zemlin received his Ph.D. In Theoretical Physics from the Humboldt University in Berlin in 2002. He completed his postdoctoral research in Cardiac Electrophysiology at SUNY Upstate Medical University in Syracuse.  In 2011, he took an Assistant Professor position at Old Dominion University in Norfolk, VA, at the Center for Bioelectrics, where he was promoted to Associate Professor in 2016.  In June 2020, he joined Washington University as the Director of the Cardiothoracic Surgery Research Lab.

Dr. Zemlin’s research focuses on mechanisms and treatments of arrhythmias.  He uses optical mapping with voltage-sensitive probes to experimentally study cardiac activity and is developing a new ablation modality based on electroporation with nanosecond pulsed electric fields.
