• List of paradoxes • Precordial exam • Pulsus alternans 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 Begin by palpating the radial or femoral arteries, feeling for a regular rhythm but alternating strong and weak pulses. Next use a blood … 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 one, like a sound and its echo. That was … See more
Pulsus alternans and pulsus paradoxus arterial waveforms
WebThis video describes the physiology underlying pulsus paradoxus in cardiac tamponade and provides a demonstration of how to measure a pulsus paradoxus. WebPulsus Paradoxus (reversed due to mechanical ventilation). This patient was hypovolemic. Criteria: The systolic blood pressure fluctuates with breathing (note that this is different than pulsus alternans, where the rhythm is regular but the systolic pressure alternates between one strong and one weak stroke volume). hudson bay southgate mall edmonton

WebPulsus paradoxus Correct D. Vascular bruit The patient is experiencing pulsus paradoxus, which is a drop in systolic blood pressure owing to increased intrathoracic pressure during inspiration. This is often the result of volume depletion or cardiac tamponade. Pulsus alternans is a pattern of amplitude change noted in end-stage left ventricular ...
