Measurement of pressure half time in aortic regurgitation Continuous wave tracing taken from the apical five chamber view illustrating the measurement of pressure half time (P1/2t) in aortic regurgitation. Here the Vmax (maximum velocity) is 479 cm/s and the slope of the Doppler tracing is 310 cm/s. Pressure half time is calculated from the slope [...]

M-mode echocardiogram from parasternal location The upper image shows the 2-D echocardiorgam in parasternal long axis view used for guiding the M-mode cut. The cursor is seen to cut the left ventricle at the chordal level, just beyond the tip of the mitral leaflets. The motion of the interventricular septum (IVS) is almost flat, due [...]

AR jet with wrap around (Click on the image for an enlarged view) Continuous wave Doppler recording showing aortic regurgitation (AR) jet (above the baseline) with a cut off at the upper end and a wrap around seen below the baseline. Here the aliasing is seen because the limit has been set just above 2oo [...]

AR and MR – Colour Doppler echocardiogram (Click on the image for an enlarged view) Colour Doppler echocardiogram showing aortic regurgitation (AR) and mitral regurgitation (MR). MR jet is seen in the left atrium (LA) in the systolic frame on the left side of the image, while AR jet is seen in the left ventricle [...]

M-Mode echocardiogram in LV dysfunction M-mode echocardiogram in left ventricular dysfunction showing reduced contractile excursions of the interventricular septum (IVS) and left ventricular posterior wall (LVPW). The vertical axis shows the distance from the transducer and horizontal axis is time. Left ventricular internal diameter in diastole (LVIDd) is increased to 6.3 cm (upper limit of [...]
