Non-invasively derived systolic time intervals for assessment of left ventricular function such as the left ventricular ejection time(LVET) and the pre-ejection period (PEP) have been extensively studied. PEP comprises the isovolumetric contraction time (ICT) and the interval from the beginning of depolarisation to the start of the systolic contraction, i.e. the electromechanical interval (EMI); it has been pointed out that the ICT should provide a better measure of left ventricular function than the PEP (12).
