Delivering succinct, clear explanations to help students easily grasp key concepts, this book provides a comprehensive, multifaceted approach to EKG interpretation for nurse practitioner and physician assistant students, as well as practicing clinicians who need a quick refresher. The second edition retains the book's systematic, physiologic approach that trains readers to follow the same steps in evaluating each EKG. It negates the need for rote memorization by facilitating a genuine understanding of EKG interpretation. Using the patient's presenting symptoms as a starting point, abundant clinical scenarios demonstrate real-life applications for interpreting EKG readings. With scores of figures and tables and more than 200 EKG tracings, this resource delivers everything physician assistants and nurse practitioners need to provide expert, quality care to their patients. New to the Second Edition: Nearly 50 new EKG tracings and accompanying case studies Basic review of clinical conditions related to common EKG abnormalities New end-of-chapter review questions to help students summarize their learning More complex clinical cases to further challenge the student and increase proficiency in EKG interpretation Additional diagnostic findings in atrial enlargement, bundle branch blocks, and ventricular hypertrophy Updated chapter contrasting premature ventricular contractions with premature atrial contractions PowerPoint supplement of case studies with EKGs and teaching points for instructors
