Pulsus tardus et parvus
In medicine, pulsus tardus et parvus, also pulsus parvus et tardus, slow-rising pulse and anacrotic pulse, is a sign where, upon palpation, the pulse is weak/small (parvus), and late (tardus) relative to its expected characteristics.
It is seen in aortic valve stenosis.
Typical findings in aortic stenosis include a narrow pulse pressure, left ventricular hypertrophy, a harsh late-peaking crescendo-decrescendo ejection systolic murmur heard best at the right second intercostal space with radiation to the carotid arteries, and a delayed slow-rising carotid upstroke (pulsus parvus et tardus). A weak S2 and/or an S4 may also be noted.
