Overview
Pulsus parvus et tardus, more commonly known as a "slow-rising" or "anacrotic" pulse, is a sign where, upon palpation, the pulse is weak/small (parvus), and late (tardus) relative to contraction of the heart.
Differential Diagnosis of the Underlying Causes of Pulsus Parvus et Tardus
Classically, it is seen in aortic valve stenosis. A meta analysis,[1] demonstrated the presence of pulsus parvus et tardus or anacrotic pulse as the most useful finding to rule in or rule out aortic stenosis in the clinical setting. The positive likelihood ratio observed across studies was 2.8 to 130.
