Atrial Flutter vs. Atrial Fibrillation: ECG Guide ⚡📈 🔁 Atrial Flutter · Rhythm: Regular · Atrial Waves: Sawtooth “F” waves · Rate: 250–350 bpm · P-Waves: Absent, replaced by flutter waves · Key: “Organized chaos” 📉 Atrial Fibrillation · Rhythm: Irregularly irregular · Atrial Waves: Erratic, low-amplitude “f” waves · Rate: 350–600 bpm · P-Waves: Absent · Key: “Disorganized chaos” 💡· Both rhythms often coexist and may transition within the same atrial substrate. · Management: Rate control (bet

❤️‍🩹⚡Atrial Flutter: Quick Guide What is it? Atrial flutter (AFL) is a re-entry arrhythmia, often in the cavotricuspid isthmus (CTI). Atypical flutter can arise from other atrial regions. Rheumatic heart disease (RHD) increases risk due to atrial dilation and fibrosis. Symptoms & Complications - Palpitations, dyspnea, fatigue, or syncope. - Complications: Stroke, tachycardia-induced cardiomyopathy, heart failure. Diagnosis - ECG: Saw-tooth P waves in II, III, aVF. - Advanced Tools: TEE, EPS, or
