BMS10-1024 - Regulation of cardiac function 1

Flashcards by Evian Chai, created more than 1 year ago

Describe/ explain mechanical events of the cardiac cycle, including changes in pressures/ volumes of the atria and left/ right ventricles, + how these correlate with heart sounds/ECG. Explain origins of heart sounds / murmurs, indicating what is heard normally and abnormalities influence of cardiac filling on force production and its mechanisms. importance of Starling’s law of the heart. ventricular function curve and how SNS impacts it

What the order of events in a single cardiac cycle, starting from atrial systole?

At what phase does ventricular pressure rise significantly?

What does the peak in LV/Aorta pressure happen after

When does ventricular pressure rapidly drop?

What causes the first sound and when does it happen?

What causes the second sound and when does it happen?

What causes the third sound and when does it happen?

What are murmurs caused by?

In the case of stenosis (narrowing of vessels), a sound in the mitral valve indicates....murmur and aortic indicates...murmur

In the case of valve incompetance (leakage), a sound in the mitral valve indicates....murmur and aortic indicates...murmur

What is endocarditis?

What are the 2 major factors affecting stroke volume?

How does sympathetic innvervation impact energy of ventricle contraction?

What does the Frank-Starling Relationship state about energy of ventricle contraction?

What does the P in the ECG graph indicate?

What indicates ventricular depolarisation on the ECG?

What indicates Ventricular repolarisation on the ECG

What is the PR interval impacted by?

What phase of the ECG shows ventricular systole?

What does the T-P on the ECG indicate?

What does the ventricular function curve show?

How does increased sympathetic innervation impact the ventricular function curve?

How does heart failure impact the ventricular function curve?
