Table 9-3

Question 1

What causes small, weak pulses?

Answer 1

Decreased stroke volume (HF, hypovolemia, severe aortic stenosis)
Increased peripheral resistance (exposure to sever hold, severe HF)

Question 2

What caused large bounding pulses?

Answer 2

1. Increased stroke volume, decreased peripheral resistance (fever, anemia, hyperthyroid, AV fistulas, PDA)
2. Increased stroke volume because of slow heard rates (brady, heart block)
3. Decreased compliance (increased stiffness) of aortic walls- aging, atherosclerosis

Question 3

What is an increased arterial pulse that has a double systolic peak?

Answer 3

Biferiens pulse

Question 4

What is a pulse that alternated in amplitude from beat to beat, but the rhythm is basically regular?

Answer 4

Pulsus Alternans

Question 5

What is a pulse that is caused by a normal beat alternating with a premature contraction?

Answer 5

Bigeminal pulse

Question 6

What is a pulse that have a decrease on quiet inspiration. Systolic pressure is decreases by more than 10 mm Hg during inspiration?

Answer 6

Paradoxical pulse
