The present is bundled with several unique features. It provides up-to-date information on electrocardiograms for almost all electrocardiographic abnormalities covers all aspects of surface electrocardiography in detail. Summaries follow all book chapters for quick revision and MCQs for self-assessment. This book will be helpful to clinicians, fellows in medicine preparing for different careers in cardiology, and ECG technicians and their teachers.The purpose of writing this book  - While teaching undergraduates, postgraduates in general medicine, and students of diploma course in cardiac instrument technology, I realized that the students did not have the knowledge of basic concepts of electrocardiography and did not know the clinical significance of various abnormalities. Students, therefore, felt that the subject was difficult to understand and of no clinical significance. Students, therefore, did not feel interested. There was a need for a book that couldsimplify the subject to the ground level for a beginner who does not know even the basics of electrocardiography. Most of the books in this field are targeted towards cardiologists with an understanding that the reader already has enough knowledge of the basic concepts of electrocardiography. MCQs are the cornerstone for learning, teaching, and evaluation. None of the books in the market gives the idea of MCQs in electrocardiography.   What problem does this book solve for the readers? - This book explains various normal and abnormal findings with the help of diagrams and illustrative electrocardiograms. Clinical implications of multiple abnormalities are discussed. This makes the subject easy to understand and to interest for a beginner. MCQs will help the readers in self-assessment. MCQs will also help teachers and examiners in evaluating the students.
