​​​The ECG is one of the most widely available diagnostic tests used in clinical practice today. This book is intended to build upon the topics covered in Starting to Read ECGs: The Basics thus allowing the reader to enhance their previous knowledge. Additional topics covered include a detailed look at calculating cardiac axis, an area often considered difficult to grasp, and alternative methods such as the various ways the heart rate can be calculated, the different criteria for determining LVH. Technical details about specific cardiac conditions, how to interpret pediatric ECGs, and the effect of medical devices on the ECG will also be discussed. Plentiful diagrams, tables and colour images used throughout to illustrate complex points in a simple and easy to understand way. The key facts section at the end of each chapter highlights the most important information and summary tables are provided to allow the book to be used as a quick reference guide. Each chapter will contain a mind map for revision and to aid dyslexic learners, practice questions and a few practice ECGs to consolidate the readers knowledge.The book tells the practitioner what they need to know clinically and doesn't assume any prior knowledge. It is ideal for junior doctors and clinicians, nurses, paramedics, students and health care professionals involved in the recording of 12-lead ECGs.
