Carotid Pulsation
Overview
How to Assess
- Palpate the common carotid arteries, located in the anterior neck medial to the sternocleidomastoid. Palpate the arteries one at a time. Care should be taken to avoid stimulating the carotid sinus.
Contour
- Rapid rate of risePremature ventricular contraction, mitral regurg, VSD, aortic regurgitation, HOCM
- Slow rate of rise Aortic stenosis
- Bisferiens pulse (double beating pulse)Aortic regurgitation
Amplitude
- Bounding pulse - strong, sustainedHypertension, hypermetabolic states
- Waterhammer / collapsing pulse: strong pulse with sudden collapse.Aortic regurgitation, patent ductus arteriosus
- Pulsus tardis & parvis: weak pulse with a delayed systolic peakAortic stenosis
- Pulsus alternans: regular alternation between strong and weak beatsLeft ventricular failure
