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 😎
