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
