[Electrocardiographic diagnosis of coronary insufficiency by means of right atrial pacing].
In 285 patients who underwent selective coronary arteriography and atrial pacing for electrocardiographic diagnosis of suspected coronary failure, the sensitivity of this test was found to be rather poor: 43% positive results for atrial pacing compared to 50% for the submaximal exercise test, 75% for the maximal exercise test and 63% for the isoprenaline infusion test. In our experience atrial pacing is of diagnostic value only where uncertainty persists after a negative isoprenaline infusion test and an exercise test likewise negative but for some reason submaximal.
