🩺 What is AV Block?

🩺 AV Block?

The condition that electricity from Atria → Ventricles through AV Node "slows down or is blocked."

👉 cause a bradycardia and risk "shock / blackout."

🧬 Pathology (understand to lack = read EKG lack!)

• 1st Degree → Delay

👉 Electricity "reaches slowly," but "goes all the way."

• 2nd Degree Type I (Wenckebach) → Fatigue

👉 AV Node "fatigue" → slowing down → then dropping 1 beat.

• 2nd Degree Type II → Structural Damage

👉 His bundle.

⚠️ Jeopardy! Risk becomes 3rd degree.

• 3rd Degree → Complete Block

👉 Electricity is lacking!

👉 Atria and Ventricles "Different People Dance" (AV Dissociation)

📊 EKG separated in 10 seconds (exam + job page)

Type Key Point

1st Degree PR > 0.20 Seconds "Long But Consistent"

2nd Type I PR "getting longer and longer" → Then QRS disappeared

2nd Type II PR Regular → QRS "dormant" ⚠️

3rd Degree P with QRS "Not Relative"

👉 Short remember:

Long gradually = Type I / dormant disappear = Type II / different world = 3rd

🚨 Red Flag that nurses need to know right away!

• HR < 50

• Low BP

• Syncope / Dark Face

• Chest pain / Dyspnea

👉 if available = Treat as Unstable Bradycardia immediately.

👩‍⚕️ Nursing (actually used in front of the job!)

1️⃣ Assessment (Do not miss)

• Vital signs every case!

• See symptoms: dizziness / seepage / panting

• Read EKG → Separate Type II vs Type I

2️⃣ Emergency Management (at the heart of this story!)

👉. If Stable

• Monitor EKG

• Find cause (medicine / K + / MI)

👉 If Unstable (Jeopardy!)

• 💉 Atropine 1 mg IV

• ⚡ Prepare Transcutaneous Pacing (TCP)

• 🚑 Prepare Crash cart / Defib

⚠️ NOTE:

• Type II + 3rd Degree → Atropine Often "Not Helping"

👉 Only Pacing!

3️⃣ Long-term Care

• Prepare to insert Permanent Pacemaker

• After wearing:

• Do not raise your arms high

• See wound / bleeding

• Capture + Sense Check

💡 Summary

💬 1st Degree

The girlfriend responded slowly... but answered every time. 😂

💬 2nd Type I (Wenckebach)

Start answering slowly... slow down... and then disappear for 1 day.

💬 2nd Type II ⚠️

Talk carefully... and "Block inaction!" (Very dangerous)

💬 3rd Degree 💔

Break up! Each person is (AV Dissociation)

🔥 Key Takeaway (Take it immediately!)

• Type II + 3rd = Do Not Wait → Prepare Pacing

• Don't waste time on Atropine if you don't respond.

• "Patient symptoms" are more important than EKG alone.

• AV Block = Risks to stop dancing
