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 ...

A person with RBBB typically does not have symptoms and may not know they have the condition. On rare occasions, a person may faint due to a severe block, though this is unlikely to occur unless other ...

Q: I recently had an electrocardiogram as part of a routine physical exam. The report said I had a bundle branch block. What does that mean? Will I need a pacemaker? A: Bundle branch blocks are ...

The ECG shows a regular wide-complex tachycardia at 120 beats per minute. Nonconducted P waves are visible, best seen in the V1 rhythm strip. This ECG meets two criteria for ventricular tachycardia ...

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 does not meet criteria for ventricular tachycardia. The R in lead V2 is larger than the R', however the criteria examine this QRS morphology change in lead V1, not lead V2. The morphology is ...

QUEBEC, QC — A new study shows that patients who harbor preexisting right bundle branch block (RBBB) face a significantly higher risk of death 2 years after transcatheter aortic-valve replacement ...

I was involved in a malpractice case a couple of years ago as a consultant. The case involved an emergency physician who was being sued for failure to make a rapid diagnosis of an ST-segment elevation ...
