Answer #1

c) Isovolumetric ventricular contraction means that the volume in the ventricles remains the same . That means only the pressure only increases not the volume in the ventricles as it works as a closed chamber.

d) Diastole takes up more time than the systole in a cardiac cycle this is because during Diastole the chambers of heart gets filled with blood which will be ejected in the systole .

This requires time and hence Diastole is longer than systole .

    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...

    what is happening in the heart during nonperfusing ventricular tachycardia. Be sure to address what is happening in the conduction system, how that affects the cardiac cycle (particularly stroke volume) and why that results in poor tissue perfusion. Why is this life-threatening? What does defibrillation do to treat it?

    1. In the left ventricle, why does isovolumetric (isometric) contraction occur during the first phase of ventricular systole? A. The bicuspid valve needs time to sit before the ventricle can eject blood. B. Ventricular pressure is greater than atrial pressure so the ventricle cannot eject blood. C. The ventricle is still filling with blood and therefore cannot eject blood during this time. D. Aortic pressure is higher than ventricular pressure and the ventricle must pressurize the blood to open the...
