This classic text, first published in 1960 and introducing at that time an entirely new approach to the study of arterial haemodynamics, provides a theoretical basis to understanding blood flow in normal and disease conditions. It examines the relationship between pulsatile pressure and flow in the arteries using a mathematical model of fluid flow principles. The current authors have developed the ground-breaking work of Donald McDonald through three editions during a period in which arterial disease has exploded as a huge clinical problem in the developed and developing world, and the content now reflects the application of the original haemodynamic discoveries to everyday clinical practice. The new edition retains the features key to the popularity of the earlier volumes - a strong scientific base, a focus on practical applications, a comprehensive coordinated style and a lack of fear in challenging established authority - but brings the content entirely up to date.
