Chandarith Cheang – ECG AV Block (Part 3)

# ECG Interpretation: AV Block

**Master the recognition and interpretation of Atrioventricular (AV) Blocks on ECG**

AV block is an important ECG finding that can range from a benign conduction abnormality to a life-threatening cardiac emergency. Accurate recognition of the type and severity of AV block is essential for appropriate clinical assessment and management.

This educational course/resource provides a **practical, systematic approach to interpreting AV blocks on ECG**, helping learners confidently distinguish between different types of conduction abnormalities.

### What You Will Learn

• Understand the normal AV conduction pathway
• Recognize **1st-degree AV block**
• Identify **Mobitz Type I (Wenckebach) 2nd-degree AV block**
• Identify **Mobitz Type II 2nd-degree AV block**
• Recognize **2:1 and high-grade AV block**
• Diagnose **complete (3rd-degree) AV block**
• Analyze PR intervals, P waves, and QRS complexes
• Differentiate Mobitz I from Mobitz II
• Recognize important ECG patterns suggesting high-risk conduction disease
• Apply a structured approach to AV block interpretation
• Understand the clinical significance of different AV block patterns

### Who Is This For?

👨‍⚕️ Medical Students
👩‍⚕️ Interns & Junior Doctors
🩺 Residents & Physicians
👩‍⚕️ Nurses & Healthcare Professionals
📚 Anyone who wants to improve their ECG interpretation skills

### Why This Course?

Instead of memorizing ECG patterns, you will learn a **step-by-step method** to examine P waves, PR intervals, QRS complexes, and the relationship between atrial and ventricular activity.

By the end of the lesson, you should be able to approach an ECG with suspected AV block systematically and identify clinically important conduction abnormalities more confidently.

**Learn ECG. Recognize AV block. Interpret with confidence.**
