This scenario-based text provides answers to urgent and emergent questions in acute, emergency, and critical care situations focusing on the electrocardiogram in patient care management. The text is arranged in traditional topics areas such as ACS, dysrhythmia, etc yet each chapter is essentially a question with several cases illustrating the clinical dilemma – the chapter itself is a specific answer to the question. This is a unique format among textbooks with an ECG focus. The clinical scenarios cover the issues involved in detecting and managing major cardiovascular conditions. Focused, structured discussion then solves these problems in a clinically relevant, rapid, and easy to read fashion. This novel approach to ECG instruction is ideal for practicing critical care and emergency physicians, specialist nurses, cardiologists, as well as students and trainees with a special interest in the ECG.
