It is a matter of pleasure for me to write the Foreword for the Principles of Electrocardiography. The book is well illustrated and electrocardiographic features of important diseases have been tabulated.

The important subject of electrocardiography has rapidly expanded and books are now available on P wave, S-A block and so forth, and an expert is often referred to as electrocardiologist.

This book covers the practical aspects of electrocardiography. it is hoped that the book will find its place as a useful synopsis.
