🫀 A-Fib vs A-Flutter — same atria, VERY different electrical problems ⚡ Atrial Fibrillation (AFib) Multiple chaotic electrical impulses fire throughout the atria. There are no true P waves, the baseline is fibrillatory, and the rhythm is irregularly irregular. Loss of coordinated atrial contraction → blood stasis → ↑ stroke risk. 🔺 Atrial Flutter (A-Flutter) A single macro-reentrant circuit (usually in the right atrium) fires in a loop. This creates sawtooth flutter waves with a more regular v
