The investigation and clinical reports of many authors in our own country and abroad have demonstrated the importance of observations on the anomalies of the ventricular complex in the electrocardiogram as regards both diagnosis and prognosis. The present volume is a systematic consideration of the subject of anomalies of the ventricular complex as a whole. The first portion of the book discusses somewhat too briefly the normal ventricular complex and its normal variations due to normal factors. The second and main portion is devoted to a study of the observed deviations from the normal. The material used consists of clinical and electrocardiographic observations in 900 hospital cardiac cases. As a control series, 418 cases are analyzed which did not show any abnormality of the ventricular complex but which comprise a wide variety of pathologic conditions clinically. In the 158 cases followed, the mortality was 15.7 per cent. Similarly, 432 cases
