          Bundle branch block in patients with severe heart failure (HF) may result in asynchronous regional left ventricular (LV) contraction. Colour Doppler tissue velocity imaging (c-TVI) allows tissue velocity profiles to be measured with a resolution of 10 ms. Normal subjects (n = 30) showed a synchronous regional longitudinal LV pattern of movement, and HF patients with bundle branch block (n = 30) showed asynchronous contraction and relaxation patterns which were quantified by c-TVI as ranging from –22 to 19 ms. This asynchronous LV contraction probably contributes to the deterioration of LV function in HF patients.
