Biphasic myocardial velocities during pre and post-ejection phases in controls and heart failure patients. Upper panel: Tissue Doppler-derived as well as schematic representation of tissue Doppler (TDI)-derived mitral annular velocities in normal controls. In blue, the predominantly positive biphasic pre-ejection (PRE), the positive component (PREp) predominates over the following negative component (PREn). In red, the predominantly negative biphasic post-ejection (POE), the negative component (POEn) predominates over the following positive component (POEp). Lower panel, representation of different concordance of isovolumic phases in heart failure patients, from left to right, normal concordance, predominantly positive PRE and predominantly negative POE, reversed PRE concordance, predominantly negative PRE and POE, reversed POE concordance, predominantly positive PRE and POE, totally reversed concordance, predominantly negative PRE and predominantly positive POE
