⚡ How Does the Heart Keep Beating in Rhythm? ⚡ The heart's conduction system is a network of specialized cells that generate and transmit electrical impulses, making your heart beat in a steady rhythm. It starts with the sinoatrial (SA) node, the heart's pacemaker, which triggers the electrical signal. This signal travels through the atrioventricular (AV) node, the Bundle of His, and Purkinje fibers, causing the heart’s chambers to contract in a coordinated manner. Together, they ensure the hear

🫀 Heart Blocks A heart block happens when there’s a delay or interruption in the electrical conduction that controls the heart’s rhythm. Here are the 4 types you need to know: 🔹 1st Degree → PR interval is prolonged 🔹 2nd Degree Type I (Wenckebach) → PR gets progressively longer, then drops a beat 🔹 2nd Degree Type II (Mobitz II) → PR is consistent, but some QRS complexes are randomly dropped ⚠️ Highest risk of progressing to 3rd degree 🔴 3rd Degree (Complete Heart Block) → No communication

What happens when the atria and ventricles stop talking? 🫣 ➡️ First-degree AV block: conduction through the AV node is delayed —> prolongation of the PR interval ➡️ Second-degree AV block: Intermittent blockage of conduction through the AV node —> intermittent P with no QRS-T ➡️ Third-degree AV block (complete heart block): All conduction through the AV node is blocked —> there is no association between P waves and QRS-T complexes 📚 Follow to stack your ECG skills, one heart block at a time 😎

🫀⚡ 4 HIGH-YIELD HEART BLOCKS Heart blocks aren’t vibes — they’re problems with how electrical signals move from the atria to the ventricles. 🧠 Quick breakdown: • 1° AV block → delayed conduction, all beats get through • 2° AV block (Mobitz I / Wenckebach) → progressive PR prolongation, then a dropped beat (AV node problem) • 2° AV block (Mobitz II) → fixed PR with random dropped beats (His-Purkinje disease ⚠️) • 3° AV block (complete) → no relationship between P waves and QRS (electrical divor

🫀 TYPES OF HEART BLOCKS A heart block is a type of arrhythmia due to electrical impulses that control the heart being disrupted. There are 4 main heart blocks you need to know: 🔴 1st Degree Heart Block → Slow conduction through AV node → EKG shows prolonged PR interval ⭐️Rhyme to Remember: “If the R is far from P, then you have a first degree.” 🔵 2nd Degree Type 1 (Wenckebach) → PR intervals gradually get longer until a QRS complex drops completely ⭐️Rhyme to Remember: “Longer, longer, longer

⚡ HYPERKALEMIA vs HYPOKALEMIA 🫀 Potassium controls resting membrane potential. Too high or too low → cardiac conduction gets unstable. 🔥 HYPERKALEMIA (⬆️ K⁺) • Peaked T waves → PR prolongation → QRS widening • Severe cases can progress to ventricular arrhythmias or arrest • Treatment (if severe/ECG changes): Calcium, insulin glucose, β₂-agonists, dialysis if needed ❄️ HYPOKALEMIA (⬇️ K⁺) • Flattened T waves, ST depression, prominent U waves • ↑ Risk of ventricular arrhythmias, especially torsa

This rhythm is Second-Degree AV Block Type II (Mobitz II) 🫀 How to recognize it FAST: • PR interval stays the same • Sudden dropped QRS complexes • No warning before the pause Key concept: The atrial impulse fires normally — but conduction fails in the His-Purkinje system. Why Mobitz II matters: • Unpredictable conduction • Can progress to complete heart block • Often associated with structural heart disease Clinical thinking: ✔️ Assess perfusion and symptoms ✔️ Monitor closely ✔️ Escalation is
