Effect of postural changes on pulsus alternans: an echocardiographic study
Chest
|May 1, 1979
Summary
This study details a patient with viral myocarditis who experienced severe left ventricular dysfunction and pulsus alternans. Postural changes, particularly standing, significantly worsened pulsus alternans, highlighting the impact on cardiac function.
Area of Science:
- Cardiology
- Internal Medicine
- Pathophysiology
Background:
- Viral myocarditis can lead to severe left ventricular dysfunction.
- Pulsus alternans, an alternating pattern of strong and weak heartbeats, can manifest in patients with cardiac compromise.
