2. Aortic valve stenosis is a hardening of the aortic valve which makes it difficult to eject blood from the left ventricle. What effect does this have on the normal electrical and/or pressure events of the cardiac cycle? In your answer, you should include terms and processes such as right atrium, tricuspid valve,right ventricle, pulmonary valve, pulmonary circulation, left atrium, bicuspid valve, left ventricle, aortic valve, systemic circulation, systole, diastole, ventricular systole/diastole, atrial systole/diastole, passive ventricular filling, “atrial kick,” isovolumic...
