Question

Match the letters on the graphs with the descriptions below. Use the letters on the EKG for electrical descriptions and the letters on the ventricular volume graph for all other descriptions. Use multiple letters if it is appropriate. ___ all valves are closed ___ atrial depolarization ___ AV valves are open ___ ventricular systole begins ___ ventricular repolarization ___ atrial contraction occurs here ___ left ventricular pressure is greater than atrial pressure but loss than aortic pressure ___ region where end systolic volume is described ___ region where semilunar values are open ___ region where greatest pressure is reached in the left ventricle ___ if the heart, rate slowed, the value in this region would increase before ventricular contraction ___ region where atrial pressure is greater than ventricular pressure

Explanation / Answer

When all the valves are closed there won't be any peak in ECG.

As Arteriar repolarization and ventricular depolarization occurs at the same time, only Ventricular values are noted.

b wave - AV nodes are open.

OMK wave - Ventricular induction

h - ventricular repolarization.

At O - Arterial contraction occurs

C - Where systolic volume is noted
