Left ventricular ejection time (LVET) is measured from blood pressure tracings as the interval from end diastole to the dicrotic notch and shows associations with left ventricular ejection fraction (LVEF) and heart failure. LVET can be measured on common carotid artery Doppler waveforms. We therefore studied the possible associations of common carotid artery LVET with LVEF measured by echocardiography and heart failure. ⋯ LVET measured on common carotid artery Doppler tracings decreases with LVEF and is strongly associated with prevalent heart failure. Based on what is known of blood pressure-measured LVET, common carotid artery Doppler waveform-derived LVET could be used to serially monitor cardiac function.
