Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats. It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis. The condition is relatively rare, and patients with the greatest risk for developing pulsus alternans … See more One explanation is that in left ventricular dysfunction, the ejection fraction will decrease significantly, causing reduction in stroke volume, hence causing an increase in end-diastolic volume. As a result, during the … See more A finding of pulsus alternans is indicative of severe left-sided heart failure. See more D.H. Lawrence elegantly describes pulsus alternans in his novel Sons and Lovers: Then he felt her pulse. There was a strong stroke and a weak … See more Begin by palpating the radial or femoral arteries, feeling for a regular rhythm but alternating strong and weak pulses. Next use a blood pressure cuff to confirm the finding: Inflate the blood pressure cuff past systolic pressure and then slowly lower cuff pressure … See more WebMeasurement of pulsus paradoxus is also useful to assess the severity of acute asthma as well as its response to therapy.
