| Popis: | The case describes a 77-year-old woman with multivessel coronary disease exhibiting marked changes of T-wave morphology induced by dipyridamole, an unusual finding in which the diagnostic accuracy in this clinical context is uncertain. Gated-SPECT imaging demonstrated severe ischaemia extending through inferior and posterolateral regions of the left ventricle with normal motility and contractile function in response to vasodilator stress. Possible underlying mechanisms and clinical implications of observed electrocardiographic changes are discussed. T-loop modifications during vasodilator stress SPECT and correlation of these changes with the amount of ischaemic injury need further evaluation. |
