Atrial fibrillation
Sudden Pain in Both Legs
A 40-year-old woman presents with acute ischemia of both lower limbs.
Panel b of the published figure. The precise recording time is not inferred from the image.
Look for
- Irregularly irregular R–R intervals.
- No repetitive organized P waves.
Where to look. Follow R–R intervals on the rhythm strip; inspect atrial activity in II and V1.
Disorganized atrial activity reaches the ventricles variably, producing irregular R–R intervals. AF can promote an atrial thrombus and embolism; an ECG alone does not prove a clot.
The published evaluation identifies mitral stenosis and an aortic embolus. No mesenteric ischemia is described.
