FACEM VAQ Exam 2005.2 – Question 6

  • Overall pass rate for this question was 45/56 (80.4%).
  • The ECG provided shows a narrow complex tachycardia with electrical alternans.
  • Examiners noted that better answers correctly diagnosed the electrical alternans but it was still possible to pass by noting that this was a narrow complex rhythm of which possible causes included a pericardial effusion post surgery
  • It was incorrect to call the rhythm atrial fibrillation. It was expected that the list of possible causes for her breathlessness would be structured so as to highlight the important or likely causes in this particular patient.
