Question

Chronic systemic hypertension results in increased afterload (“pressure load”) on the left ventricle of the heart, affecting the pressure-volume relationship of the left ventricle. What effect does this have on the normal electrical and/or reassure event of the cardiac cycle?

In your answer, you should include terms and processes such as right atrium, tricuspid valve, right ventricle, 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 ventricular contraction, ventricular ejection, isovolumic relaxation, stroke volume, preload, afterload, pressure-volume loop, and physiologic vs. pathogenic cardiac hypertrophy

Explanation / Answer

In normal cardiac cycle the superior and the inferior venacava are responsible to bring the blood in to the right atrium and from there the bolld enters thr right ventricle. The left atrium collects blood from the pulmonary vein which is oxygen rich blood and then the blood enters the left ventricle. The walls of the left ventricle is thickercompared to the right ventricle as it produces force to pump the blood to the systemic arteries.
