Fig. 2From: Prediction of response to cardiac resynchronization therapy using left ventricular pacing lead position and cardiovascular magnetic resonance derived wall motion patterns: a prospective cohort study Type I and type II wall motion patterns. Modified American Heart Association models demonstrating (a) a type I wall motion pattern, with dotted lines indicating homogenous wave fronts anteriorly and inferiorly towards the lateral wall, and (b) a type II wall motion pattern, with an inferior line of block (green line) and dotted line indicating an anteriorly directed wave front and late inferior wall motionBack to article page
