  • Abstract
  • Look Inside

A 56-year-old woman with a 23 year-history of myotonic dystrophy was admitted to our hospital be-cause of dysphagia and aspiration pneumonia. On ad-mission, patient's ECG showed Ist degree of atrioven-tricular block and elongation of QRS (133 msec.). On the third hospital day, abnormal Q wave abruptly ap-peared in aVL associated with elevation of ST segment in V2 and V3, reverse T wave in Ⅰ, Ⅱ, Ⅲ, aVF and V 2-6 leads on ECG. Echo cardiogram demonstrated asynergy at the apex and septal wall. Coronary angio-graphy was normal. Left ventricular ejection fraction determined by left ventriculography decreased to 47.4 %.
