The new book from the author of the original classic text Hurst's the Heart! This innovative reference supplies a system for interpreting individual electrocardiograms (EKGs) based on fundamental principles of electrocardiography and vector concepts, rather than relying on a physician's ability to recollect the shapes and patterns of a multitude of tracings. Highlights Grant's method of measuring the direction of electrical forces in the modern era of cardiology! Enabling physicians to make a differential diagnosis, Interpreting Electrocardiograms ·establishes a scientific method by representing spatially oriented vectors that can be visualized and measured ·considers the heart's electrical forces, zero potential plane, and transitional pathway ·outlines the location and anatomic features of the heart chambers and conduction system ·discusses the use of Einthoven's bipolar extremity leads, Bayley's triaxial system, Wilson's unipolar chest leads, and Goldberger's unipolar extremity leads to determine the spatial orientation of electrical forces ·includes examples of normal EKGs ·discusses preexcitation, postexcitation, and Osborn, epsilon, and Brugada waves ·covers left and right ventricle hypertrophy due to diastolic and systolic pressure overload, myocardial infarction, ventricular conduction abnormalities, pericarditis, digitalis effect, and electrolyte disturbances ·and more! Providing a step-by-step method for interpreting EKGs using basic principles and vector concepts, Interpreting Electrocardiograms is a groundbreaking reference for cardiologists, internists, family and primary care physicians, and medical school students in these disciplines.
