Prevalence and potential mechanisms of sustained ventricular arrhythmias during dobutamine stress echocardiography: a literature review.
Sustained ventricular tachycardia during dobutamine stress echocardiography is a rare complication of dobutamine stress echocardiography. It may be related to reduced left ventricular function and prior myocardial infarction but cannot be used as a sensitive or specific sign for myocardial ischemia. The clinical significance of dobutamine stress echocardiography-induced sustained ventricular tachycardia is uncertain, and this condition probably does not represent an adverse prognostic sign.
