Sensitivity and specificity of the behaviour of the R-amplitudes under exercise are investigated at an additional lead position on the anterior chest wall, which in previous multi-electrode-examinations showed a higher sensitivity than the conventional Wilson-leads V 4 and V 5. For the criterion "increase of R-amplitudes" could certainly be confirmed a higher sensitivity at the additional lead position, the bad specificity both at the conventional and at the additional lead position allows, however, only the inclusion of the decrease of the physiological R-amplitude into the exclusion diagnostics of the chronic ischaemic heart disease.
在前胸壁的一个额外导联位置研究了运动时R波振幅行为的敏感性和特异性,在先前的多电极检查中,该位置显示出比传统威尔逊导联V4和V5更高的敏感性。对于“R波振幅增加”这一标准,在额外导联位置确实可以确认更高的敏感性,然而,无论是在传统导联位置还是额外导联位置,特异性都很差,这使得仅能将生理性R波振幅降低纳入慢性缺血性心脏病的排除诊断中。
