A right bundle branch block (RBBB) involves a delay in the electrical impulses reaching the heart’s right ventricle, which can affect the heart’s ability to pump blood effectively. While RBBB doesn’t ...
Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. But if the pathway is blocked, the impulses may move slower than normal or irregularly.
This ECG shows ventricular pacing. Note the pacer spike prior to each QRS complex, most apparent in leads V5 and V6. The P waves appear sinus in origin and have no association with the QRS complexes ...
