Implication

Does not support pulsus alternans as a heart failure severity marker; leaves open its laterality, inducibility, and prognostic role.

Structured PICO

Population

36 adult patients in heart failure due to a variety of cardiopulmonary diseases, and a separate review of echophonocardiographic records of 100 patients with congestive cardiomyopathy (total n=136).

Intervention

Measurement of left- and right-sided systolic time intervals from simultaneous dual echocardiograms of both semilunar valves.

Outcome

Presence and prevalence of unilateral or bilateral pulsus alternans in the systemic and pulmonary circulations.surrogate

Pulsus alternans can be unilateral or bilateral and is frequently induced by ventricular premature complexes, but its presence does not appear to correlate with measurable differences in heart failure severity.
