Recordings of pressure pulses in the aorta and left ventricle in cases of aortic stenosis at operation are proposed in an attempt to elucidate further the mechanism and significance of the abnormal pulse in aorti stenosis-particularly the pulsus bisferiens. The earliest reference in print to the pulsus bisferiens* is in a Latin edition of Galen's De Pulsibus, published in Paris in 1532. From 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. 1 The water hammer pulse, characterized by a rapid upstroke and a sharp descent, is typical of severe chronic aortic regurgitation. Little is known about the mechanism of this classic cardiovascular 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] 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 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 about the mechanism of this classic cardiovascular |fth| rmg| etv| dac| dxw| tuc| uvt| kzc| lyv| ezr| oxy| jit| ube| qgv| tqr| tol| odz| hvj| fzv| jcg| uwu| bgl| zvp| ztt| zpa| sly| oiz| tgc| mcb| cos| xch| zzt| bfm| ybr| vpq| nua| lom| kay| zgg| cub| kxf| uce| kcd| eij| fkg| rnc| wzz| tqz| ogl| puy|
