EP on EP Episode 45 - Sex Differences in Atrial Fibrillation-EP on EP Episode 45

Video Transcription

Video Summary

Dr. Ann Gillis discusses the effect of sex on atrial fibrillation (AFib) in this video segment. She explains that sex hormones, such as estrogen, can affect cardiac electrophysiology, leading to differences in action potential duration and QT lengthening. Women also tend to develop AFib later than men, but catch up post-menopause due to the development of coronary artery disease and hypertension. Women also tend to have more fibrosis in the atria, which can impact treatment and outcomes. Dr. Gillis emphasizes the need for further investigation into these sex differences in AFib.
