Background: Spectral power of fetal heart rate variability is related to fetal condition. Previous studies found an increased normalized low frequency power in case of severe fetal acidosis. Aims: To analyze whether absolute or normalized low or high

Time-frequency analysis of heart rate variability (HRV) provides relevant clinical information. However, time-frequency analysis is very sensitive to artefacts. Artefacts that are present in heart rate recordings may be corrected, but this reduces th

The diagnostic value of the Gee-oculopneumoplethysmography test for the detection of hemodynamically significant carotid artery obstructions has frequently been questioned due to the rather low agreement with arteriography. The kappa-corrected diagno

In patients with multilevel arterial obstructive disease, assessment of the severity and location of the pathology is a difficult diagnostic problem. As reported recently, the intra-arterial pressure in the common femoral artery may become normal, al

In order to assess vasospastic ischemic disease objectively 41 patients with primary Raynaud's phenomenon and 21 normal volunteers were investigated noninvasively by digital systolic blood pressure and digital skin temperature measurements before and

Summary Uterine artery blood flow velocity waveforms (FVW) were recorded longitudinally in normal pregnancies (n = 41) at 4-week intervals from a gestational age of 18 weeks onwards. Furthermore, reproducibility of the uterine artery FVWs and the rel

A decreased renal function is rather common after renal transplantation. The causes of this decreased function are diverse and difficult to differentiate. Yet, duplex examination, and especially quantitative Doppler spectrum analysis of the blood vel

The aim of the study was to investigate whether increased peripheral resistance which is supposed to exist in patients with primary Raynaud's phenomenon, can be quantified by using parameters of Doppler spectra of flow in the ulnar and radial arterie

The value of digital systolic blood pressure (DBP) and flow (DBF) measure ments for a quantitative diagnosis of Primary Raynaud's Phenomenon (PRP) was evaluated by comparing the results obtained in 10 patients and 20 normals. Digital skin temperature
