First-Degree AV Block:🔍 A fixed delay in conduction at the AV node. Not a blockage, but a slowdown. 🔹 Diagnostic ECG Criteria ▸PR Interval: >200 ms (≥ 1 large box). ▸Rhythm: Regular sinus. ▸Conduction: 1:1 (Every P → QRS). ▸Constancy: Fixed PR interval. 💡 Clinical Pearls ▸Often Benign: Asymptomatic; common with high vagal tone, athletes, or medications (BB, NDHP-CCB, digoxin). ▸Context Matters: Assess for underlying heart disease, ischemia, or electrolytes.

A First-Degree AV Block is characterized by a prolonged conduction time through the AV node, resulting in a PR interval greater than 0.20 seconds. Every P wave is still followed by a QRS complex, meaning no beats are actually dropped—it's just a delay. ​Key ECG Finding: PR Interval > 0.20 seconds (or > 5 small boxes) ​Significance: Usually asymptomatic and benign, but important to monitor as it can sometimes progress to a higher-grade block. ​#EKG #ECG #heartblockage #HeartBlock #cardiology | Ho

💓 Let’s talk about AV Blocks! 💓 Understanding heart blocks is essential for every healthcare professional 👩‍⚕️👨‍⚕️ 🫀 4 Types of AV Block: 1️⃣ First-degree AV block – 🔹 PR interval > 0.20 sec, all beats conducted. 2️⃣ Second-degree Type I (Mobitz I / Wenckebach) – ⏳ PR interval gets longer… until a beat is dropped! 3️⃣ Second-degree Type II (Mobitz II) – ⚠️ Sudden dropped QRS without PR change! 4️⃣ Third-degree AV block – 💔 Complete AV dissociation… atria & ventricles beat independently! ⚡
