  1. Results expressed as mean ± standard deviation. EDV (ml) = End diastolic volume in millilitres. ESV (ml) = End systolic volume in millilitres. EF % = Ejection fraction as a percentage of blood ejected per cardiac cycle. Ea (cm/sec) = Peak early mitral annular tissue velocity recorded by Doppler tissue imaging. E Acc (cm/sec2) = Rate of acceleration of blood across the mitral valve in early diastole. E/A = Ratio of peak early diastolic flow over peak late diastolic flow. Et VI cm = Time velocity integral of early diastole in centimetres At VI cm = Time velocity integral of late diastole in centimetres. Time to Acc (ms) = Time to peak acceleration of early diastole in milliseconds. Heart Rate (ms) = R to R interval in milliseconds IVRT (ms) = Isovolumic relaxation time.
