Background: In 1972, Manseau et al. and Kubli et al. described an undulating wave form alternating with a flat or smooth baseline fetal heart rate (FHR) in severely affected, Rh-sensitized and dying fetuses. This FHR pattern was called 'sinusoidal' because of its sine waveform.
30 Σεπ 2015 · Internal FHR monitoring using a fetal electrode (usually known as scalp electrode, but it can also be applied to the breech) evaluates the time intervals between successive heart beats by identifying R waves on the fetal electrocardiogram QRS complex, and therefore measures ventricular depolarization cycles.
1 Μαΐ 1982 · Fetal tachycardia is defined as a baseline fetal heart rate (FHR) of 160 bpm or greater lasting 10 min or longer. The baseline FHR abnormality can be associated with prematurity, maternal...
A specific definition of SHR was made in order to elucidate its clinical significance. According to this definition, 41 tracings from 23 publications were classified as being either true SHR, equivocal, or a heart rate pattern other than SHR.
Fetal conditions associated with SHR pattern: SHR pattern has been reported with the following fetal conditions: (1) severe fetal anemia of several etiologies; (2) effects of drugs, particularly narcotics; (3) fetal asphyxia/hypoxia; (4) fetal infection; (5) fetal cardiac anomalies; (6) fetal sleep cycles; and (7) sucking and rhythmic movements...
fetal condition. A rare but distinct baseline FHR pattern, of undulant an extremely significant finding and implied severe fetal jeopardy and impending fetal death. wave form, was originally described by Manseau and associates’ in severely affected Rh-sensitized fetuses.
1 Ιουλ 2004 · We propose a definition of a low-frequency, sinusoidal rhythm having: 1) a stable baseline FHR (fetal heart rate) of 120 - 160 bpm; 2) a possible variation of 20 - 30 bpm; 3) a frequency of...
