In 76 patients suffering from heart diseases and 19 healthy men simultaneously the chest leads V(2), V(4) and V(5) were recorded and the bipolar lead CM(6) (Manubrium sterni-Apex cordis, 6th intercostal space) transmitted telemetrically during increasing exercise load on the bicycle ergometer. The lead CM(6) was most similar to chest lead V(5) with regard to R/S-ratio, ST-depression, form and amplitude of the T-wave, QX-QT-ratio and ST-elevation. ST-depressions of V(5) were found nearly without exception in CM(6), mostly more pronounced. Ascending ST-depressions are more frequent in CM(6) than in V(5), in single patients also ST-depressions with horizontal or downward slope. ST-elevations registrated in V(2) and V(4) are not reliably reproduced in CM(6). It is concluded that the wireless transmission of the bipolar chest lead CM(6) is sufficient for the diagnosis of coronary insufficiency during exercise,
