(A)Mid-myocardial, mid-systole short axis MRI tagging image in a patient with CRT device showing sufficient tag quality for strain analysis. (B)Reconstructed electrical activation times during intrinsic activation showing RV preceding LV activation. (C)Synchronized electrical activation of the same patient during biventricular pacing.
