ECG Test 8-22-15

Bundle-Branch Block & Chamber Enlargement

QuestionAnswer
What does intraventricular mean? Within the ventricle
The left main bundle branch of the heart is divided into what? Two fascicles, and anterior fascicle and a posterior fascicle
How does normal depolarisation occur in the right bundle branch and left bundle branch? Electrical impulses travel through the right bundle branch and left bundle branch and fascicles at the same time causing simultaneous depolarization of the right and left ventricles
What is a normal QRS duration? .10 seconds or less
What happens to an electrical impulse when one bundle branch is blocked? The electrical impulse travel down the intact bundle depolarizing that ventricle first and then the impulse progresses through the interventricular septum to depolarize the other ventricle
What is depolarization of one truck ventricle before the other called? Sequential depolarization
What is a result of sequential depolarization? Depolarization of the ventricles is delayed, resulting in a wide QRS complex of .12 second or greater
Which bundle branch block is most common? Right bundle branch block or RBBB
What population is left bundle branch block most commonly seen in? Elderly individuals with diseased hearts
What is the most common cause of left bundle branch block? Hypertensive heart disease
What treatment is indicated for bundle branch block? Specific treatment is usually not indicated for bundle branch block
What does knocking in the QRS signify? BBB bundle branch block
How do you determine if BBB is LBBB or RBBB? Look at v1 through v6 to make a determination
List five criteria for complete LBBB Wide QRS; notched R waves in V4 V5 V6; wide slurred S in v1 v2 v3; secondary ST/T wave changes, could get left axis deviation
Five criteria for Right Bundle Branch Block
Which leads are the right precordial leads? V1, v2, v3
Which leads are the left precordial leads? V 4, v5, v6, v7
