Fig. 3From: In silico screening method for non-responders to cardiac resynchronization therapy in patients with heart failure: a pilot studyElectric potentials in Purkinje fiber networks. Here, color indicates electric potentials. Red means electrically activated whereas blue means resting state. a. In normal ventricular conduction model, most parts of the ventricles activate almost simultaneously. b. In the LBBB model, most of the left part of the Purkinje fiber network remains electrically inactivated. LBBB = left bundle branch blockBack to article page
