Recognition
- • Sawtooth flutter waves (best in II, III, aVF)
- • Atrial rate ~300
- • Often 2:1 block → 150 bpm
Key findings
- • Regular ventricular rhythm if fixed block
Clinical importance
- • Stroke risk like AF
- • Often degenerates to AF
Management pearls
- • Rate control / DC cardioversion
- • Anticoagulation
- • Ablation (cavotricuspid isthmus) — high success
