ECG studies provide extensive and valuable information for clinicians. In some patients, such as those who have experienced an ST elevation myocardial infarction, an accurately interpreted ECG is one of the most effective guides to treatment and management. This book describes a quick, and practical 5-step method of ECG interpretation that can be used to diagnose all important clinical conditions. This book is intended for non-cardiologist clinicians and health care providers such as emergency medicine physicians, internists, intensivists, family physicians, and nurses in monitored and intensive care units.
