The in-utero environment is relatively hypoxic, but fetal physiologic adaptation assures adequate tissue oxygen supply. Fetal reactions to acute or chronic hypoxia are different and are modified by the preceding fetal condition. Acute fetal hypoxia episodes are often not preventable. By contrast, good obstetric care during labor may prevent poor ...

Hypertrophic cardiomyopathy (HCM) is a relatively common genetic disorder (1:500) inherited as an autosomal dominant trait. It is caused by mutations in any one of 10 genes encoding protein components of cardiac sarcomere. Some theoretically calculated risks exist when patients with HCM become pregnant. The physiologic increase of cardiac output ...

Non-invasive fetal electrocardiography (ECG) can be used for prolonged monitoring of the fetal heart rate (FHR). However, the signal-to-noise-ratio (SNR) of non-invasive ECG recordings is often insufficient for reliable detection of the FHR. To overcome this problem, source separation techniques can be used to enhance the fetal ECG. This study ...
