ECG Image Index

The following ECG categories contain hundreds of ECGs that range from the sublime to the ridiculous, from simplicity to complexity, and from boring to fascinating. Many of the ECG rhythm strips come from the collection of the late Dr. Alan Lindsay, master teacher of electrocardiography. Most of the 12- and 6-lead ECGs were recorded at LDS Hospital in Salt Lake City, Utah. Marquette Electronics has also given permission to use ECG rhythms and diagrams from their educational posters. Each of the ECGs has an interpretation and many have additional explanations that help explain the diagnosis. Feedback is encouraged using the feedback form provided with this website.
