A common cliché states that if you stand still every 10 years, you will find yourself in the forefront of fashion. Thus it seems with the analysis of ventricular function. It has been recognized for many years that incoordinate or non-uniform contraction reduces global left ventricular (LV) function. Wiggers demonstrated in 1922 that stimulation from a ventricular focus rather than supraventricular produced a reduced pulse pressure, prolonged isometric contraction, and systolic ejection time in normal hearts. Although regional wall motion abnormalities were recognized early in ischaemic heart disease, it was also demonstrated later that it occurs in dilated or hypertrophic cardiomyopathy.1 However, the realization that asynchronous wall motion due to delayed activation such as in the presence of a left bundle branch block profoundly affected global function did not take place until more recently.2 Developments in cardiac imaging
