Does ventricular dyssynchrony on echocardiography predict response to cardiac resynchronisation therapy? A randomised controlled study

ObjectiveTo determine the value of echocardiography in predicting response to cardiac resynchronisation therapy (CRT).MethodsThis is a prospective randomised study that recruited patients with (group 1) and without (group 2) echocardiographic evidence of mechanical dyssynchrony. 73 heart failure pat...
