Pulsus tardus et parvus, also pulsus parvus et tardus, slow-rising pulse and anacrotic pulse, is weak (parvus), and late (tardus) relative to its expected characteristics. It is caused by a stiffened aortic valve that makes it progressively harder to open, thus requiring increased generation of blood pressure in the left ventricle.
8452-5. Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure (a drop more than 10 mmHg) and pulse wave amplitude during inspiration. Pulsus paradoxus is not related to pulse rate or heart rate, and it is not a paradoxical rise in systolic pressure.
Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats. [1] It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis. The condition is relatively rare, and patients with the greatest risk for developing pulsus alternans include those with heart ...
In particular, there may be a slow and/or sustained upstroke of the arterial pulse, and the pulse may be of low volume. This is sometimes referred to as pulsus parvus et tardus. [12] [24] There may also be a noticeable delay between the first heart sound (on auscultation) and the corresponding pulse in the carotid artery ('apical-carotid delay ...
Lower limb. Foot. Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves, but there are minor variations in some of the details.
[citation needed] Their existence on lower extremity is more serious that on the upper ones. [citation needed] The most common reason for irritative phenomena is a lesion of a central motoneuron, but in the presence of asymmetrical findings then a diagnosis of amyotrophic lateral sclerosis should be considered.

Pulsus bisferiens. Pulsus bisferiens, also known as biphasic pulse, is an aortic waveform with two peaks per cardiac cycle, a small one followed by a strong and broad one. [1] It is a sign of problems with the aorta, including aortic stenosis and aortic regurgitation, as well as hypertrophic cardiomyopathy causing subaortic stenosis. [1]
In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. [5] Anatomists restrict the term leg to this use, rather than to the entire lower limb. [6] The thigh is between the hip and knee and makes up the rest of the lower limb. [5] The term lower limb or lower extremity is commonly used to describe ...
