This 81-year-old woman just underwent surgery for small bowel obstruction. 15 years ago, she suffered from a myocardial infarction, requiring a 2-vessel aorto-coronary bypass. 

She is presently in the post-anaesthetic care unit, and has developped the following arrhythmia:

•  Ventricular tachycardia, 133/min with one fusion complex     

In favor of ventricular tachycardia:

  – Wide QRS complex (140 msec)
  – AV dissociation (presence of fusion complex)
  – Negative QRS concordance in the chest leads

The patient received IV Amiodarone, and the arrhythmia subsided. Her condition remained stable: 

• Sinus rhythm with sinus arrhythmia and occasional premature supraventricular and ventricular complexes
• Low voltage QRS
• Possible anterior infarction, age undetermined
• Non-specific T wave abnormality
