Figure 1

M-mode echocardiograms. Arrows indicate LV end-diastolic and end-systolic dimensions. Normal contraction with LV hypertrophy 13 years before admission (A), dilated left ventricle with abnormal wall motion before CRT (B), decrease in LV dimensions and slight improvement in LV contraction 1 week after CRT (C), and normalized LV dimensions and further improvement in LV contraction 3 years after CRT (D) were seen (fractional shortening 33%, 7%, 11%, and 20%, respectively). Of note, posterior wall motion deteriorated (broken arrows).
