The Department of Medicine and Section of Cardiology at the University of Chicago welcome you to the Marion-Arnsdorf ECG Project!

For students, researchers and physicians, this site is designed to serve as a complete course in cardiac electrophysiology starting from the very basic concepts of cellular potentials all the way through arrhythmia diagnosis using electrocardiography. Each Learning Unit serves as a mini-course to further the understanding of these complex concepts.

This web-based learning platform was conceived by Dr. Morton Arnsdorf, MD, MACC and was created with philanthropic support from his patient and friend, Stanley W. Marion.

We hope that you find this course fun and useful for your studies!
