Otis: A Textbook by Indian Cardiologists, for Indian Students

Otis is regarded as the first comprehensive textbook on cardiology authored entirely by Indian cardiologists. Conceived and designed by Dr M. Khalilullah after nearly six decades as a teacher of cardiology, the book offers an exhaustive and contemporary coverage of all major areas of cardiovascular disease, combining academic rigour with clinical practicality.

A distinctive feature of Otis is its strong focus on self-assessment. Each chapter is followed by carefully structured multiple-choice questions, with answers provided at the end of the book, enabling students and practising cardiologists to independently evaluate their understanding. This format has made it particularly valuable for examination-going students.

Widely appreciated by senior cardiologists in India and abroad, Otis has come to be recognised as a definitive cardiology textbook by Indian authors. Priced affordably, it reflects Dr Khalilullah’s enduring belief that high-quality medical education should remain accessible, practical, and rooted in the realities of Indian clinical practice
