A 36 year old woman presents with palpitations for an hour. She is pain free and normotensive.
Describe and interpret her ECG (100%)
FACEM VAQ Exam 2009.2 – Question 7
- The overall pass rate for this question was 48/67 (71.6%).
- ECG features as below
- Pass criteria
- Narrow complex tachycardia rate 150-180/min, regular
- No P waves, right axis, rSR pattern V1-3 consistent with incomplete RBBB with T wave inversionand ST depression V1-5
- Young haemodynamically stable female—likely to be SVT with aberrant conduction leading to RBBB pattern – possibly re-entrant pattern
- ST-T changes more likely to be conduction disturbance than ischaemia in clinical context, but should be considered
- Fail criteria:
- Incorrect rate
- Narrow complex tachycardia described as VT
- ST changes described as ischaemia without consideration of conduction abnormality
