Figure 3 Conventional M-mode echocardiogram recordings obtained at rest, during low-level exercise echocardiography (LLEE), low-dose dobutamine echocardiography (LDDE) and at follow-up (FU) in a patient with inferior myocardial infarction. Images were acquired in parasternal short axis view. End-diastolic values were recorded at the beginning of QRS complex and in end-systolic values on top of T-wave. Absolute systolic thickening was 0.1 mm at baseline, 2.9 mm during LLEE 4.8 mm during LDDE, and 2.4 mm at baseline on the follow-up echocardiogram.
