For a busy clinician in the Emergency Department, the ability to spot a lethal condition is critical. This book fills a gap in ECG teaching: it is intentionally graphic and nontechnical. The ECG patterns, gathered from patient records and from the files of physicians at the Harvard-affiliated hospitals, represent the range of ECG pathologies that hospitalists, internal medicine physicians, family medicine physicians, and emergency medicine physicians must recognize. Rapid Interpretation of ECGs in Emergency Medicine quizzes the reader by using figures/image matching to diagnoses rather than text-based MCQs.
