Attenuation of pulsus alternans during coronary angiography may indicate further deterioration of ventricular function.
May indicate worsening ventricular function during angiography; hypothesis-generating from a single case.
Following coronary angiography in a patient with cardiomyopathy and pulsus alternans, we observed a transient but marked attenuation of the alternation in pulse pressure associated with an elevation in pulmonary artery pressure. Attenuation of pulsus alternans has been rarely reported and may represent further deterioration of ventricular function.
