This study was undertaken to establish normal values for the systolic atrioventricular plane motion (AVPM) from base to apex during dobutamine-atropine stress echocardiography (DASE) and to compare them with those of patients with coronary artery disease. The AVPM was measured at baseline, low dose and peak dobutamine-atropine infusion in 20 patients referred for coronary angiography and in 20 control subjects. Atrioventricular plane motion was measured at the posterior, anterior, septal, and lateral positions of the mitral annulus in the apical 2- and 4-chamber views by an observer blinded to clinical and angiographic data. In healthy subjects undergoing DASE, AVPM initially increased but subsequently decreased to below baseline values at peak stress. Atrioventricular plane motion at any stage and the changes therein during DASE were within the normal reference interval in the majority of patients. In conclusion, AVPM decreased during DASE in healthy subjects and was not a sensitive marker of coronary artery disease.
