Atrial fibrillation with an uncontrolled ventricular response Intermittent right bundle branch block - rate dependent This ECG shows atrial fibrillation with an uncontrolled ventricular rate. There ...

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 atrial fibrillation with an uncontrolled ventricular rate. There are two QRS complexes that become wide in a right bundle branch block pattern. This can occur at fast heart rates when ...

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 ...

The diagnosis is NSR, first-degree AV block, 3:1 AV block, Mobitz type II, and high-degree AV block. The rhythm is regular with a rate of 30 beats/min. The QRS complex duration is normal (0.08 sec) ...
