What is the difference between pulsus alternans and Pulsus paradoxus?

Pulsus alternans is a pulse pattern in which there is alternating (beat-to-beat) variability of pulse strength due to decreased ventricular performance. This is sometimes seen in patients with severe CHF. Pulsus paradoxus indicates an exaggeration of the normal reduction of systolic blood pressure during inspiration.

What does pulsus bisferiens mean?

A double pulse noticed during systole in the peripheral pulse is called pulsus bisferiens. This is derived from the Latin word, which means strike twice (bis=twice, ferio=strike). It is also called a biphasic wave.

What is the difference between pulsus bisferiens and dicrotic pulse?

The main distinguishing feature of pulsus bisferiens is that two peaks are seen in systole. In contrast, a dicrotic pulse is characterized by one peak in systole and the other in diastole. Dicrotic pulse is seen in the low cardiac output state, sepsis, and cardiac tamponade.

What is pulsus pulsus alternans?

Pulsus alternans is a physical finding characterized by a regular alternation of the force of the arterial pulse. It almost invariably indicates the presence of severe left ventricular systolic dysfunction.

When do you see pulsus alternans?

Pulsus alternans is usually found in severe left ventricular systolic dysfunctions due to cardiomyopathy[3], coronary artery disease[2], systemic hypertension[2], and aortic stenosis[4].

Why is pulsus paradoxus called paradox?

In 1873, Kussmaul first described pulsus paradoxus in three patients with pericardial disease. Kussmaul called the finding “paradoxical” because the pulse of his patients disappeared during inspiration even though the apical beat persisted throughout the respiratory cycle.

Where is Pulsus Bisferiens best felt?

felt better in peripheral arteries is pulsus alternans .

What does Pulsus Bisferiens feel like?

Pulsus bisferiens describes the presence of an exaggerated “double pulsation” in the arterial pulse. While the arterial pulse is normally dicrotic, consisting of a percussion wave and a tidal wave, the individual waves are not typically visible or palpable at the bedside. The pulse looks and feels like a single wave.

Why does Pulsus Bisferiens cause aortic stenosis?

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.

What is water hammer pulse also known as?

Watson's water hammer pulse (whp), also known as collapsing pulse, cannonball pulse or pulsus celer, is used to describe a pulse with a rapid upstroke and descent, characteristically described in aortic regurgitation.

What is a pulsus paradoxus?

Moderate to severe cardiac tamponade, and occasionally constrictive pericarditis, induce hemodynamic changes that enhance the inspiratory fall in systolic blood pressure. This exaggerated drop in systemic blood pressure during inspiration is termed pulsus paradoxus (waveform 1 and waveform 2).

What is pulsus paradoxical?

Introduction. Pulsus paradoxus refers to an exaggerated fall in a patient's blood pressure during inspiration by greater than 10 mm Hg.

What is the meaning of alternans?

Introduction. Electrical alternans is defined as alternating QRS amplitude that is seen in any or all leads on an electrocardiogram (ECG) with no additional changes to the conduction pathways of the heart.

What is Paradoxus?

Systolic blood pressure normally falls during quiet inspiration in normal individuals. Pulsus paradoxus is defined as a fall of systolic blood pressure of >10 mmHg during the inspiratory phase.
