Each concept and abnormality has been explained with the help of a diagram and exemplary electrocardiogram

The clinical relevance of various abnormalities is discussed which makes the subject interesting for a beginner

Each chapter is followed by a summary for quick revision and several MCQs which will help the readers in self-evaluation
