It is commonly used to detect abnormal heart rhythms and investigate the cause of chest pains. It is important for clinicians to recognise and interpret ECG patterns accurately to ensure correct diagnosis and effective treatment. This book is step by step guide to performing and interpreting ECGs. Divided into 11 sections, the text begins with an overview of the history of ECGs and the physiology of the heart and its conduction system. The next chapters discuss the basics of ECG, the leads and their placement, and normal ECG morphology. The following sections cover systematic interpretation of ECGs, arrhythmias, paediatric ECG interpretation and congenital anomalies, and finally, differential diagnosis. The second edition of this practical guide has been fully revised to include the latest advances in the field. Line diagrams and clinical images further enhance learning.
