To further enhance the accuracy of treadmill testing incorporation of echo is applied directly to view the heart after exercise.
Set images are taken prior and post exercise and compared, to view heart function. Identification of cardiomyopathies (heart muscle disease) or ischaemia can be made.
If a patient experiences shortness of breath on exertion, pulmonary pressures can also be assessed post exercise to exclude a cardiac component. The patient is normally required to fast three hours prior to minimise airway hazards.
