Adjustment to the data acquisition window for patients with atrial fibrillation. a In patients with atrial fibrillation (or other irregular rhythms), we adjust the data acquisition window such that the imaging readout is completed prior to the end of the shortest R–R interval between heart beats. b Examples of LGE images in a patient with atrial fibrillation. The top row shows in which the data acquisition window was set too long (> than the shortest R–R interval). There is substantial blurring of the subendocardium, and it is not clear if an infarct is present. The bottom row from the same patient in whom data acquisition was set to be less than the shortest R–R interval. Image sharpness is improved and the infarct is easily delineated from the blood pool and adjacent normal myocardium
