Jerky pulse

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Authoring team

The arterial pulse in patients with hypertrophic cardiomyopathy is described as jerky.

The pressure wave is characterised by:

  • a rapid upstroke due to the vigorous contraction of the hypertrophic left ventricle
  • as the volume of the left ventricle decreases there is a sudden obstruction to the left ventricular outflow
  • outflow obstruction results in a rapid fall in arterial pressure
