🫀Complete heart block, aka third-degree atrioventricular (AV) block occurs when there is a complete interruption or blockage in the electrical signals between the upper chambers (atria) and lower chambers (ventricles). Because signals are getting blocked, there is no association between the P waves and the QRS complexes causing them both beat independently of each other. The atria maintain their own rhythm, and the ventricles establish a separate rhythm.⁣ ⁣ 𝗦𝘆𝗺𝗽𝘁𝗼𝗺𝘀⁣ Patients with compl

💓 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! ⚡
