ABNORMALITIES OF THE ARTERIAL PULSE

Question 1

Pulse pressure 30-40mmHg, pulse is smooth and rounded

Answer 1

Normal​

Question 2

Pulse pressure is diminished, and pulse feels weak and small. Upstroke
may fell slowed, peak prolonged

Answer 2

small, weak pulses

Question 3

name this arterial pulse:

1. decreased stroke volume (heart failure, hypovolemia, and severe aortic stenosis),
2. increased peripheral resistance (exposure to cold and CHF)

Answer 3

small, weak pulses

Question 4

Pulse pressure is increased and pulse feels strong and bounding. Rise
and fall feel rapid, brief peak

Answer 4

large, bounding pulses

Question 5

name this arterial pulse:

1. Increased stroke volume, decreased peripheral resistance, or both (fever, anemia,
   hyperthyroidism, aortic regurgitation, AV fistulas, patent ductus arteriosus)
2. Increased stroke volume because of slow HR (as in bradycardia and complete heart
   block)
3. Decreased compliance (increased stiffness) of aortic walls (as in aging or atherosclerosis)

Answer 5

large, bounding pulses

Question 6

Increased arterial pulse with a double systolic peak

Answer 6

Bisferiens Pulse

Question 7

name this arterial pulse:

1. Pure Aortic Regurgitation
2. Combined aortic stenosis and regurgitation
3. Hypertrophic Cardiomyopathy (less commonly palpable)

Answer 7

Bisferiens Pulse

Question 8

name this arterial pulse:

Pulse alternates in amplitude from beat to beat even though the rhythm is
basically regular. When the difference between stronger and weaker beats is slight, it can be
detected only by this instrument? what can this indicate?

Answer 8

Pulsus Alternans

sphygmomanometry

Indicates left ventricular failure and usually accompanied by left-sided S3

Question 9

name this arterial pulse:

May mimic pulsus alternans; caused by a normal beat alternating with a premature contraction. Stroke volume of the premature beat is diminished in relation to that of the normal beats, and the pulse varies in amplitude accordingly

Answer 9

Bigeminal Pulse

Question 10

name this arterial pulse:

Detected by a palpable decrease in pulse’s amplitude on quiet inspiration. If less pronounced, need a BP cuff

systolic pressure decreases by how much during inspiration?

Answer 10

paradoxical pulse

10 mmHg

Question 11

this type of pulse is found with these disease?

pericardial tamponade, constrictive pericarditis, and obstructive lung disease (less
common)

Answer 11

paradoxical pulse
