Bisferious pulse

Bisferious pulse is a type of pulse that is characterized by two strong systolic peaks separated by a mid-systolic dip. This type of pulse is often associated with certain cardiovascular diseases, such as aortic regurgitation and hypertrophic cardiomyopathy.

Definition

A bisferious pulse is a pulse wave that has two distinct peaks in the systolic phase. The term "bisferious" comes from the Latin words "bis", meaning "twice", and "ferio", meaning "I strike". This type of pulse is also sometimes referred to as a "pulsus bisferiens".

Causes

The bisferious pulse is typically caused by conditions that result in an increased stroke volume or decreased peripheral resistance, leading to a rapid ejection of blood from the left ventricle during systole. These conditions can include aortic regurgitation, hypertrophic cardiomyopathy, and patent ductus arteriosus.

Clinical significance

The presence of a bisferious pulse can be a significant clinical finding, as it may indicate underlying cardiovascular disease. It is often detected during a physical examination, through palpation of the radial or carotid arteries. The detection of a bisferious pulse can lead to further diagnostic testing, such as echocardiography, to determine the underlying cause.
