Hello friends
Today in this video we will know about Conduction system of heart and conduction block
Conduction system made up of 
SA node
AV Node
Bundle of his
RBB
LBB
Purkinje fiber 
While Left bundle divided in two parts anterior and posterior division
So impulse start from natural pacemaker of heart SA node and stimulate whole heart tissue and contraction start in heart and pump out blood from heart 
When there is block in conduction system heart can't work properly
Intraventricular Conduction block are right bundle branch block, left bundle branch block , anterior fascicular and posterior fascicular block
Most common is Left anterior fascicular block bec it is thin and long structure while posterior fascicular block is rare bec it is thick and short structure
Isolated conduction block is benign and had no problems but when conduction block occur with heart attack,heart failure, cardiomyopathy, aortic valve disea, hypertension it had poor prognosis and increased mortality and morbidity
For isolated Conduction block no need any treatment while in case of associated heart disease treatment of heart disease is required
Thanks
