Cardiovascular Flashcards
1
Q
What is pulse pressure?
A
The difference between systolic and diastolic pressure.
2
Q
How would aortic stenosis affect pulse pressure?
A
It would decrease the pulse pressure because the end systolic volume would be increased
3
Q
What increases pulse pressure?
A
- A less compliant aorta (occurs with aging)
- Increased stroke volume
4
Q
What is the sequence of cardiac electrical activation?
A
SA node Atria AV node Bundle of his R&L bundle branches Purkinje fibres
