What does LBBB stand for?

What does LBBB stand for?

• A. Left Bundle Branch Block
• B. Left Basal Branch Block
• C. Long Baseline Body Balance
• D. Left Brain Baroreflex Block

Answer: (A)

LBBB stands for a disruption in the heart’s electrical conduction specifically in the left bundle branch. The left bundle branch is part of the pathway that rapidly conducts impulses to the left ventricle. When it’s blocked or delayed, the left ventricle activates later than the right, often making the QRS complex wider on an ECG and sometimes producing a characteristic pattern. This is the standard medical term for that condition, so it’s the correct choice. The other options don’t describe a recognized cardiac conduction term—they’re either nonsensical or unrelated to heart conduction.
