Ergometry (stress testing, exercise testing)
̶Work load examination – measurement of ECG and other parameters depending on the increasing degree
of work load on the ergometer
̶In addition to ECG, the following can be recorded:
̶O2 consumption, CO2 output, blood pressure, blood samples (mainly lactate)
̶Types of ergometers
̶Bicycle ergometer – load mainly on the lower half of the body
̶Rowing machine – upper body load
̶Rump ergometer – exercise bike for hands, para/quadriplegia
̶Master´s step
̶Treadmill
̶Can be used in:
̶Sports Medicine
̶Rehabilitation medicine
̶Cardiology

application of low workload in order to increas tissue perfusion and improve joints mobility
recording of resting values
exposure of examined person to graduated physical work
workload of low intensity supporting catabolites removal (lactic acid), helping heart rate
recovery, reducing vertigo and collapses (due to after-work hypotension)
follow-up after exercise
