The presence of left ventricular(LV)dyssynchrony seems mandatory for a positive response to CRT. Currently,only patients with wide QRS complexes are considered for CRT, although patients with narrow QRS complexes may also have LV dyssynchrony. In the present study, the incidence of LV dyssynchrony was prospectively evaluated in 64 patients with heart failure and narrow QRS complexes using tissue Doppler imaging.展开更多
