What does the intraventricular conduction system
compose of? -
ANSWER-Right bundle branch and the left main bundle
branch that divides into two fascicles
What are the two fascicles the left bundle branch divides
into? -
ANSWER-1. anterior fascicle
2. posterior fascicle
When one of the bundle branches is blocked, how does
,the electrical impulse travel? - ANSWER-The electrical
impulse travels down the intact bundle, depolarizing the
ventricle first and then the impulse progresses through the
inter ventricular septum to depolarize the other
ventricle
-delay in depolarization causes a QIDE QRS (>0.12)
,How is the difference between a right and left bundle
branch determined? - ANSWER-With a 12 lead EKG
What is the most common cause of a R bundle branch
block? -ANSWER-CAD
-coronary artery disease
What are causes of a right bundle branch block? -
ANSWER-1.
,hypertensive heart disease
2. congenital heart disease
3. myocarditis
4. HF
5. cardiomyopathy
What is the most common cause of a left bundle branch
block? -ANSWER-Hypertensive heart disease
What is a premature ventricular contraction? - ANSWER-A
PVC is apremature ectopic impulse that arises below the
bundle of HIS in the ventricles
Why do PVC's occur? - ANSWER-As a result of enhanced
automaticity of a focus in the ventricles, reentry involving
, the ventricles or triggered
activity occurring in the ventricles during repolarization
,What are the characteristics of a PVC? (5) - ANSWER-1.
premature
QRS
2. A P wave that isn't associated with the PVC
3. QRS is wide and isn't similar in the morphology
4. the ST segment and T wave slope in the opposite
direction from the
main QRS deflection
5. the pause associated with the PVC is compensatory
A run of three or more PVC's constitutes what? -
