This book presents an invaluable symptoms-based approach to sports cardiology for sports medicine physicians, primary care physicians, and cardiologists. Edited by an authority in the field, the text offers sought-after insight on caring for the cardiac health of athletes. The first part of the book covers diagnostic tools and treatments. Readers will learn the fundamentals of the preparticipation exam, cardiac screening, and ECG use. Cardiac imaging and electrophysiologic testing are addressed as well. To aid with diagnosis, the second part of the book is organized by symptom and sign. Chapters on common signs such as shortness of breath, chest pain, and syncope provide guidance on which tests to perform and how to formulate a clinical workup. Referral is also noted. The third part of the book ties the text together and outlines specific cardiac diseases and disorders. Sudden cardiac arrest, congenital heart disease, and hypertension are among the topics discussed. Case studies are featured throughout to further understanding and the integration of concepts into daily practice. With contributions by both sports medicine physicians and cardiologists, this timely book bridges the gap between disciplines and is an unparalleled resource for those looking to effectively manage the cardiac health of active patients.
