🎧 FREE MSRA PODCAST – Atrial Flutter: Sawtooth Rhythms & Stroke Risk


In this high-yield cardiology episode, we dissect Atrial Flutter—a rapid, regular arrhythmia with that iconic sawtooth ECG pattern. 🫀⚡ Whether you're revising for the MSRA or brushing up on core cardiology, this one's packed with exam gold.


🧠 What you’ll learn in this episode:
– 🔁 Definition: Organised re-entrant circuit in the atria causing rapid contractions
– 📉 ECG hallmark: “Sawtooth” flutter waves, best seen in leads II, III, and aVF
– 🧪 Causes: Structural heart disease, post-cardiac surgery, hyperthyroidism, COPD, alcohol misuse
– 🚨 Symptoms: Palpitations, dyspnoea, fatigue, dizziness – sometimes even syncope
– 📊 Stroke risk: Lower than AF but still significant – managed with CHA₂DS₂-VASc scoring
– ⚙️ Management essentials:
 • Rate control: Beta-blockers, calcium channel blockers
 • Rhythm control: Electrical cardioversion or antiarrhythmics
 • 💉 Anticoagulation: Based on stroke risk
 • 🔥 Catheter ablation: Highly effective for typical flutter (~95% success)
– 🩺 Investigations: ECG, echo, thyroid function tests, ambulatory monitoring if paroxysmal
– 🧠 Mnemonic alert: Think “Sawtooth + 2:1 AV block = Atrial Flutter”
