SceeU defines the pulsus bisferiens as follows: quotBoth percussion and tidal waves are well represented, but the latter, instead or being rounded and sustained, forms a sharp angle. Moreover, the second wave begins low and the two waves reach the same level, or nearly so. Pulsus bisferiens is the exception, however, as it is most easily palpated in the peripheral arterial system, e.g. The radial artery. Discover the world's research 20+ million members.

In respect to this, what is the cause of Pulsus Paradoxus?Many things can cause pulsus paradoxus, which is a dip in blood pressure during inhalation. While it's usually due to a heart or lung condition, such as asthma, it can also be the result of heavy blood loss. Pulsus paradoxus in pericardial disease.
Furthermore, what are three signs of cardiac tamponade? The three classic signs of cardiac tamponade, which doctors refer to as Beck's triad, are:
- low blood pressure in the arteries.
- muffled heart sounds.
- swollen or bulging neck veins, called distended veins.
Besides, what happens to blood pressure during inspiration?
During inspiration, the negative intrathoracic pressure causes pooling of blood in expanding pulmonary vessels and a delay of flow to the left ventricle. Thus, systolic pressure falls as cardiac output falls momentarily. The following procedure checks for a paradoxical pulse.
What is Beck's triad?
Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, an emergency condition wherein fluid accumulates around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds.
Pulsus bisferiens or double pulse refers to a wave pattern where there is the presence of two systolic peaks that can be seen in pressure tracings of the ascending aorta, the aortic arch, and the carotid artery.
It can occur in patients with
- aortic valve pathology: aortic regurgitation with or without concurrent aortic stenosis
- severe obstructive hypertrophic cardiomyopathy.
- aortic dissection: rare 1
