ECG Introduction

THE ALAN E. LINDSAY ECG LEARNING

CENTER

Frank G. Yanowitz, M.D

Professor of Medicine

University of Utah School of Medicine

Medical Director, ECG Department

LDS Hospital

Salt Lake City, Utah

This tutorial is dedicated to the memory of Dr. Alan E. Lindsay, master teacher

of electrocardiography, friend, mentor, and colleague. Many of the excellent

ECG tracings illustrated in this learning program are from Dr. Lindsay's personal

collection of ECG treasures. For many years these ECG's have been used in

the training of medical students, nurses, housestaff physicians, cardiology

fellows, and practicing physicians in Salt Lake City, Utah as well as at many

regional and national medical meetings. It is an honor to be able to provide this

tutorial on the World Wide Web in recognition of Dr. Lindsay's great love for

teaching and for electrocardiography.

This interactive ECG tutorial represents an introduction to clinical

electrocardiography. ECG terminology and diagnostic criteria often vary from

book to book and from one teacher to another. In this tutorial an attempt has

been made to conform to standardized terminology and criteria, although new

diagnostic concepts derived from the recent ECG literature have been included

in some of the sections. Finally, it is important to recognize that the mastery of

ECG interpretation, one of the most useful clinical tools in medicine, can only

occur if one acquires considerable experience in reading ECG's and correlating

the specific ECG findings with the pathophysiology and clinical status of the

patient.

The tutorial is organized in sections based on a recommended "Method" of ECG

interpretation . Each section provides some didactic teaching points, often linked

to illustrations, and an interactive quiz. Beginning students should first go

through the sections in the order in which they are presented. Others may chose

to explore topics of interest in any order they wish. The ECG's range from the

sublime to the ridiculous, from simplicity to complexity, and from boring to

fascinating. It is hoped that students will be left with some of the love of

electrocardiography shared by Dr. Lindsay.

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.
