The OxyconAlpha with option ECG is a software-driven, medical device for exercise measurements, including ECG ST Segment Analysis and/or ECG Stress Analysis. It measures the human response to increasing workloads with emphasis on the gas exchange parameters. Measurements include ventilation, oxygen uptake, carbon dioxide excretion, heart rate and derived parameters. The results of the tests, including the ECG wave forms, can be viewed on the computer screen and can be printed during the test. The test results can be saved on the computer hard disk for further referral or report generation purposes.

The OxyconAlpha with option ECG interfaces to a testsubject via a mouthpiece or a face mask and ECG electrodes. The OxyconAlpha with option ECG interfaces to a peripheral ergometer or treadmill. The patient population is 4 age and older,

The OxyconAlpha with option ECG is capable of performing computerized ECG interpretation during resting condition.
