Atrial Flutter : Conduction & Ventricular Response Atrial flutter is a macro-reentrant atrial tachycardia with a characteristic sawtooth pattern on ECG, most visible in leads II, III, and aVF. The atrial rate is typically regular and ranges from 250-350 bpm. The ventricular response is determined by the refractory period of the atrioventricular (AV) node, leading to fixed conduction ratios. 🔹 2:1 Block: Most common; ventricular rate ~150 bpm 🔹4:1 Block: Target with pharmacologic rate control �
