Echocardiographic assessment of wall motion in ST‐segment alternans during coronary angioplasty

ST alternans occurs in the setting of severe and extensive myocardial ischemia. In this particular case, ST alternans occurred well after the onset of ischemia‐induced left ventricular dysfunction. There is no echocardiographic evidence of beat‐to‐beat variation in contractility to correspond to thi...

Zusammenfassung:	ST alternans occurs in the setting of severe and extensive myocardial ischemia. In this particular case, ST alternans occurred well after the onset of ischemia‐induced left ventricular dysfunction. There is no echocardiographic evidence of beat‐to‐beat variation in contractility to correspond to this ST‐segment phenomenon. Further studies of left ventricular function during ST alternans in patients are needed to determine whether this finding applies to all patients with is‐chemic heart disease.
