常見心電圖 ECG Criteria

RBBB
QRS duration > 120 ms
rsR’ “bunny ear” pattern in the anterior precordial leads (leads V1-V3)
Slurred S waves in leads I, aVL and frequently V5 and V6

Mariot Practical Electrocardiography
Lead V1 Late intrinsicoid (R' peak or lateR peak), M-shaped QRS (RSR'); sometimes wideR or qR
Lead V6 Early intrinsicoid (R peak), wide S wave
Lead I Wide S wave

LBBB
QRS duration > 120 ms
Absence of Q wave in leads I, V5 and V6
Monomorphic R wave in I, V5 and V6
ST and T wave displacement opposite to the major deflection of the QRS complex
