Answer

Dobutamine is a beta-receptor agonist that increases both heart rate and contractility. In combination with echocardiography, regional wall abnormalities and, thus, ischemia may be assessed. The negative and positive likelihood ratios of dobutamine stress echocardiography for detecting coronary artery disease are 0 and 4.5, respectively. Of note, avoid dobutamine stress echocardiography testing in patients with a history of ventricular tachyarrhythmia (see image below).
