Question

At the beginning of left ventrical systole when the atrio-ventricular valve has just closed so that all valves are closed (there can be more than one answer)



a) left ventrical blood volume will stay constant and left ventrical blood pressure will increase while we measure the QRS wave in ECG and observe the second heart sound.

b) left ventrical blood volume increases and left ventrical blood pressure will remain constant while we measure the T wave in ECG and have just oberved the first heart sound.

c) left ventrical blood volume will stay constant and left ventrical blood pressure will increase while we measure the QRS wave in ECG and have just observed the first heart sound.

d) blood pressure in the aorto will increase because of ventricular contraction and we will measure the P wave in ECG.

e)left ventrical blood volume will increase and left ventrical blood pressure will remain constant while we measure the QRS wave in ECG and observe the first heart sound.
