Question

1. Mr. Ayers's pulse is described as "thready." What might this indicate with respect to this patient's stroke volume?

2.Mr. Ayers's HR increased from 110 to 130 bpm. What effect will this have on his cardiac output? Explain your reasoning.

3.Beginning with the concept of end diastolic volume (EDV), explain the effect that the fluid in the pericardium is having on the stroke volume of Mr. Ayers's heart.

4. Muffled heart sounds are quieter and less distinct. Explain how changes in EDV can result in muffled heart sounds

Explanation / Answer

1) Thready pulse is a weak pulse. It can be obliterated easily by applying a small pressure. It shows that the stroke volume is lower than normal.

2) The normal heart rate is between 60-100 beats per minute. Heart rate of over 100 is called as tachycardia. When heart beats faster, there is less venous return as less ventricular filling leading to decrease in stroke volume.
