Pulsus Bisferiens - StatPearls - NCBI Bookshelf
2023年7月2日 · Pulsus bisferiens is commonly seen in mixed aortic disease with severe aortic regurgitation and hypertrophic cardiomyopathy. The incidence of aortic regurgitation is high in the fourth to sixth decade of life, increases with age, and is more common in the elderly.
Pulsus Bisferiens - PubMed
2023年7月2日 · Pulsus bisferiens is associated with severe aortic disease accompanied by aortic regurgitation and hypertrophic obstructive cardiomyopathy (HOCM). Providers often confuse this with the dicrotic pulse. The main distinguishing feature of …
Pulsus bisferiens - Wikipedia
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]
A Unified Mechanism for the Water Hammer Pulse and Pulsus Bisferiens …
The bisferiens pulse in severe aortic regurgitation has been attributed to a Venturi effect that occurs in the ascending aorta in mid-systole due to the high flow produced by ventricular ejection. The water hammer pulse, characterized by a rapid upstroke and a sharp descent, is typical of severe chronic aortic regurgitation. Little is known ...

2020年11月20日 · Pulsus bisferiens, a classic cardiovascular sign, has been described in severe aortic regurgitation, hypertrophic cardiomyopathy, subaortic stenosis, and contained rupture of a thoracoabdominal aortic aneurysms. 5 However, its hemodynamic mechanism is incompletely understood and likely varies in different disease states.
Aortic Valve Regurgitation: A Comprehensive Review
2018年8月1日 · Aortic regurgitation (AR) is the diastolic reversal of blood flow from the aorta into the left ventricle. AR can be owing to a primary disease of the aortic valve (AV) or abnormalities of the perivalvular apparatus and structures such as the aortic root and ascending aorta.

2018年3月1日 · We demonstrate a novel pulsatile hemodynamic mechanism: a forward moving suction wave. This unifies the pathogenesis of the bisferiens pulse and water-hammer pulse. The carotid bisferiens pulse and the radial water hammer …

2024年3月11日 · Pulsus bisferiens is a two-peak waveform during systole that is most commonly seen in severe aortic regurgitation and hypertrophic obstructive cardiomyopathy (HOCM). Although its mechanism is not fully understood, the early wave component is attributed to rapid left ventricular ejection, while the late component is suspected to be caused by the ...
