|
When is Atrial Depolarization on an EKG? |
During the QRS complex |
|
|
What is the Sinoatrial Node? |
SA Node. This is where Cardiac depolarization begins. |
|
|
What is the Atrioventricular node? |
AV Node. This is the 'bridge' between the atria and ventricles for electricity. From the SA node electricity comes here and then goes to the AV bundle (Bundle of His) |
|
|
What is the atrioventricular bundle? |
Bundle of His This is after the AV node and splits into bundle branches going off to each ventricle |
|
|
What are bundle branches? |
Electrical pathways (left and right) after the AV Bundle that are on the ventricles |
|
|
What comes after bundle branches in the electrical pathway of the heart? |
Purkinje Fibers, also known as subendocardial fibers |
|
|
Coronary Sinus
|
brings blood into rt. atrium from myocardium of the heart
