The PR interval is measured from the start of the P wave (atrial depolarization) to the start of the QRS complex (ventricular depolarization). 👉 It represents the time it takes for the electrical impulse to travel from the SA node, through the atria, AV node, and into the ventricles. 📏 Normal range: 0.12–0.20 seconds (3–5 small boxes on ECG paper). ⚠️ Too short (<0.12 sec): May suggest an accessory pathway (like WPW). ⚠️ Too long (>0.20 sec): Think first-degree AV block or conduction delay. Knowing the PR interval helps you spot subtle conduction problems before they turn into major rhythm issues. #PRInterval #ECGInterpretation #CardiacRhythms #CVICUSchoolhouse #CriticalCareNurse #nurse #icunurse #newnurse

For those wondering about Mr Wenckebach 🎓 In Mobitz type I AV block, the PR interval progressively increases until we see a non-conducted P wave (blocked beat) - this is called Wenckebach phenomenon. Mobitz Type II AVB: there are intermittent non-conducted P waves but the PR interval remains constant. ✅ Save for later ☺️

Comment “ECG” And I’ll send you the EKG Interpretation Cheat Sheet with everything you need to break down rhythms step by step 🫀 You don’t need to memorize the whole strip Just understand what each wave means The P wave represents atrial contraction The QRS complex shows ventricular contraction The T wave reflects ventricular relaxation 📈 Ask yourself: • What is the heart rate • Is the rhythm regular or irregular • Is there a P wave before every QRS • What is the PR interval (should be 0.12 to 0.20 seconds) • Is the QRS narrow or wide 🧠 These five questions will guide your rhythm interpretation Save this post and tag a classmate who needs this breakdown 📚 More guides in the link in bio #nclexrn #ekginterpretation #nursingstudent #nclexprep #cardiacnursing #ecg #rhythmstrip #clinicalskills #printerval #qrscomplex

Key intervals include: - *P-R interval*: Time from P wave start to QRS start (0.12-0.20 sec) - *Q-T interval*: Time from QRS start to T wave end (varies with heart rate) - *S-T segment*: From S wave end to T wave start (usually isoelectric) . #microscopeforever2024 #microbiologyworld247 #neetfuturedoctors720 #neetallinformation720

AV Blocks – Progressive Conduction Failure: 1. First-Degree AV Block: Consistent delay at the AV node. Prolonged PR interval (>200 ms). Every impulse eventually reaches the ventricles. 2. Mobitz I (Wenckebach): Progressive PR interval lengthening until a P wave is blocked (a QRS is dropped). Typically at the AV node. Usually benign. 3. Mobitz II: Intermittent, sudden failure of conduction without preceding PR prolongation. Block typically infranodal (Bundle of His or below). Carries significant risk of progression to complete heart block. --- ✨ @dailycardiology #Cardiology #ECG #AVBlock #HeartBlock #MedEd Medical SinusRhythm Wenckebach CardiacConduction

Struggling with Heart Blocks in ECG? 🤯 Stop memorizing blindly! Think of them as "Relationship Problems" and you will never confuse Wenckebach with Mobitz again. ​Here is the breakdown for your exams: ​1️⃣ First Degree Block: The Long Distance Relationship. Husband (QRS) comes home late every day, but he is consistent. (Prolonged PR interval >200ms, but fixed). ​2️⃣ Second Degree, Type 1 (Wenckebach): The Slow Breakup. Husband comes later... and later... and later... until one day he doesn't show up! 🏃💨 (PR lengthens progressively until a QRS is dropped). ​3️⃣ Second Degree, Type 2 (Mobitz II): The Ghosting. Everything seems normal and on time, then suddenly—NO SHOW without warning! This is dangerous. (Constant PR interval, then sudden QRS drop). ​4️⃣ Third Degree (Complete Block): The Divorce. Wife (P-wave) and Husband (QRS) are living completely separate lives. No connection at all. (AV Dissociation). ​📌 Save this Reel for your NEET PG / USMLE quick revision! 👇 Share with a study partner who needs to see this hack.
