@criticalcarernfriend: New post here 🚨 ICU SCENARIO 🚨 Your patient complains of: 😓 Fatigue 💫 Lightheadedness 🫀 “I feel like my heart is skipping beats.” Vitals: ❤️ HR 68 bpm 🩸 BP 124/76 🫁 SpO₂ 97% The monitor shows: ⚠️ Regular rhythm ⚠️ Every P wave followed by a QRS ⚠️ PR interval >0.20 seconds What rhythm are you looking at? 👀👇 ✅ First-Degree AV Block In first-degree AV block, every atrial impulse conducts to the ventricles—it’s just delayed. Key ECG clues: 🫀 PR interval >200 ms 🫀 Regular rhythm 🫀 1:1 AV conduction Common causes: 💊 Beta blockers 💊 Calcium channel blockers 💊 Digoxin 🫀 Increased vagal tone 🫀 Inferior MI ⚡ Electrolyte abnormalities The biggest lesson? 🚨 Not every conduction abnormality requires intervention. The real question is: Why does the patient have it? 👇 COMMENT: Would you simply monitor this patient, or would you start looking for an underlying cause immediately? #nurse #nurselife #rn #nursing #nursetok
