Credit for the high quality of ECG reproduction in this book goes to Gordon Grindy
and his colleagues at Marquette Electronics, Inc. My partner, Wes Moses, proofread the
text and ECG interpretations, and I am also grateful to Dr. Hans Traberg who made
useful suggestions for the 3rd edition. I again acknowledge that Marilyn Taylor is a
patient woman, and I appreciate her forbearance during this writing adventure.
