For over four decades the Marriott name has been a synonym for quality education in electrocardiography. As Practical Electrocardiography 's new author, Galen Wagner proved a worthy successor to Barney Marriott with an innovative Ninth Edition of this classic text. The new Tenth Edition features two-color ECGs so readers can see ECG strips as they appear in clinical practice. Extensive updates to chapters on ischemia and infarction provide a current view of these critical areas. The text is revised with more consistent terminology, and a complete approach to the topic that gives the reader a better understanding of electrocardiography in today's medicine.
