- Carotid (listen for bruit, evaluate for upstroke: brisk, delayed, normal)
- Abdominal and femoral pules (strength, bruit)
- Peripheral pulses (absent to bounding scored 0-4+, symmetry, irregularity)
*Radial and femoral pulses are especially important if pt undergoing cath or other procedure requiring arterial access. Need to know baseline

68

At least 10cm
69
venous waveforms
reflects right atrial presystolic contraction, occurs just after the ECG P wave and precedes the first heart sound (S1)
a wave
70
prominent venous a wave suggests
Reduced RV compliance
71
Cannon a wave
AV dissociation and right atrial contraction against a closed tricuspid valve
72
The presence of cannon a waves in a patient with wide complex tachycardia identifies the rhythm as
ventricular in origin
73
Describe the a wave in JVP eval
reflects right atrial presystolic contraction, occurs just after the ECG P wave wave, precedes S1
74
The a wave is absent in what rhythm
AF
75
Venous pulsations
Reflects the fall in right atrial pressure after the a wave
Atrial diastolic suction created by ventricular systole pulling the tricuspid valve downward
In normal persons this is the predominant waveform in the jugular venous pulse
X descent
76
Venous pulsations
Interrupts the x descent as ventricular systole pushes the closed valve into the right atrium
C wave
77
Venous pulsations
Represents atrial filling, occurs at the end of ventricular systole and follows just after S2
Height determined by atrial compliance and by volume of blood returning to right atrium
V wave

V wave is accentuated in
TR
79

82
Rise in venous pressure (or its failure to decrease) with inspiration
Kussmaul sign

- Restrictive CMP
- Pulmonary embolism
- RV infarction
- Advanced systolic heart failure
*Seen with right sided volume overload and reduced RV compliance
83
Kussmaul sign
Describe:
When can this be seen? General and specific.
Rise in venous pressure (or failure to decrease) with inspiration
Seen with right sided volume overload and reduced RV compliance
Constrictive pericarditis, restrictive CMP, PE, RV infarction, advanced systolic HF
84
Describe the pathophysiology behind Kussmaul sign
Normally the inspiratory increase in right sided venous return is accommodated by increased RV ejection, facilitated by an increase in the capacitance of pulmonary vascular bed
In states of RV diastolic dysfunction and volume overload, the RV cannot accommodate the enhanced volume and the pressure rises
Increased pulmonary vascular resistance may also limit the RV ejection and contribute to phenomenon
85

Firm and consistent pressure over the right upper quadrant for at least 10 seconds
Refrain from valsalva or holding breath during procedure, can falsely elevate

87
+ abdominojugular reflux sign can predict
- heart failure

95
In pt's with POTS does blood pressure usually fall on standing?

97
