[Significance of isolated atrial stimulation as a stress test in comparison with bicycle ergometry]

On 77 patients was performed a comparative examination of load ECG on the bicycle ergometer and isolated atrial stimulation for the diagnosis of an ischaemic heart disease. With 80.5% in the estimation of the two methods with regard to the correct diagnostic classification in relation to the number of patients in the random test a good accordance is the result. With the two methods nearly identical results can be yielded and as to small number of patients with clear indication even an supplementation of the provokation tests performed up to now can be spoken of, since additional diagnostic references to an ischaemic heart disease are possible. But the isolated atrial stimulation cannot supersede the usual load ECG in the diagnostics of the ischaemic heart disease an account of the great methodical expenditure.
