title: Variability of inotropic and chronotropic response during dobutamine stress echocardiography and possible implications for diagnostic accuracy.
abstract: Chronotropic and inotropic response patterns were assessed during dobutamine stress echocardiography. Three heart rate response patterns were noted: nonresponders (48% of patients), slow responders (30% of patients), and fast responders (21% of patients). There was no relation between heart rate and contractile response.
