Clinical significance of an equivocal signal-averaged electrocardiogram.
Patients with an equivocal signal averaged electrocardiogram (SAECG) had less heart disease and better prognosis than patients with overtly abnormal SAECGs. An equivocal SAECG should not prompt further invasive diagnostic testing for ventricular tachycardia unless other clinical risk factors are present.
