[Tei index evaluated by M-mode echocardiography in patients with dilated cardiomyopathy].

Objectives: The Tei index obtained by the Doppler method is effective for analysis of global cardiac dysfunction. M-mode recordings of the aortic valve and mitral valve can also provide this index.

Methods: Forty-two patients with cardiomyopathy (idiopathic 15 and ischemic 27) with left ventricular ejection fraction < 40%, and 85 normal subjects were enrolled in the study.
