ABSTRACT
The article studies the link between ischaemia, left ventricular (LV) untwisting and changes in filling pressure during dobutamine stress echocardiography (DSE). It notes that no link between LV twist and ischaemia has been documented in the past although the extent of infarct has been associated with abnormal LV twist. It describes the study of 216 routine DSE done in Brisbane, Queensland in 2009. Patients with abnormal filling pressure response are found to have impaired LV untwisting rate during isovolumic relaxation time (IVRT).
