Abstract: Dobutamine stress echocardiography has become widely accepted as a safe, reliable and cost effective modality for the evaluation of patients with suspected myocardial ischemia or for prognostic stratification and outcome assessment in patients with known coronary artery disease, While the benefits of this means of cardiovascular testing are very clearly apparent, it is important to understand and recognize possible complications. This paper discusses the occurrence of sustained, nonischemic ventricular tachycardia during dobutamine stress echocardiography in the absence of functional, physiologic or anatomic evidence of coronary artery disease or cardiomyopathy.
