The diagnosis of many cardiovascular diseases can
benefit from imaging during a cardiac stress test. The
purpose of this study was to develop a low-cost exercise
device that could be used within the confines of an MRI
bore during a cardiac MR scan and also provides measures
of work. The device was designed to create exercise
stress via a stepping motion by the subject in a supine
position while minimizing unwanted chest movement and
upper body translation. Our pilot testing results
confirmed substantial increase in heart rate (+85%),
cardiac output (+100%), mean aortic flow (+65%) and mean
pulmonary artery flow (+%101) post-exercise.
