Basic Electrocardiography

The significantly expanded second edition of this important textbook provides a comprehensive overview of the basics of electrocardiography. Each chapter is revised, and the book includes new chapters that focus on pacemakers, low voltage, pulmonary embolism, and hypothermia. The book is intended to help students in all health care delivery fields and at all levels of training to learn the basic concepts of interpreting electrocardiograms. It concisely covers the essential components of electrocardiography (ECG or EKG) and helps readers identify a number of conditions, including arrhythmias, bifascicular blocks, and heart attacks. Chapters are constructed to introduce basic themes, show examples from actual patient tracings, and provide practice through self-test electrocardiograms that reinforce the concepts taught in the chapter. Additionally, practice tracings build on the information provided in earlier chapters as well as on the features of the current one. Designed for the clerkship student, resident, or even the practicing professional who wants to brush up on EKG particulars, the second edition of Basic Electrocardiography is a user-friendly guide to one of medicine's most useful tools.
