Cardiographic Technician on Instagram: "🚑 Right Bundle Branch Block (RBBB) – Clinical DeepDrive 1. Basic Concept •Bundle branches carry conduction to the ventricles. •In RBBB, conduction through the right bundle is delayed/blocked → right ventricle depolarizes late. •This produces a wide QRS (>120 ms) with characteristic morphology. --- 2. ECG Features of RBBB 👉 Easy rule: “RSR’ in V1, Wide S in V6” 1. QRS Duration ≥ 120 ms (broad). 2. Right chest leads (V1–V2): •Classic RSR’ (M-shaped, rabbit

Cardiographic Technician on Instagram: "This ECG finding shows PR segment depression + ST segment depression (sagging downsloping type). This is the classic sign of acute pericarditis. 👉 Key points: PR segment depression → most specific for acute pericarditis. ST segment elevation (concave) or generalized ST changes are also found. PR segment depression appears first. ✅ Final Answer: Acute Pericarditis"
