A noninvasive method for measuring the antenatal human fetal systolic time intervals with the use of the transabdominal fetal electrocardiogram and Doppler cardiogram is described. Unique interactive computer routines were developed for rapid and accurate determination of the pre-ejection period (PEP), ventricular ejection time (VET), PEP/VET ratio, and fetal heart rate (FHR). Thirty normal patients were monitored between 20 and 40 weeks of gestation. A regression analysis of the fetal systolic time intervals and FHR against gestational age was done. PEP and PEP/VET ratio were significantly correlated to the gestational age, while VET and FHR were not

Advanced extrauterine pregnancy occurs rarely and may present diagnostic difficulty. Failure to induce uterine contractions during oxytocin infusion is a well-established diagnostic technic. The present case suggests that additional newer technics for fetal assessment, including sonography, unstressed monitoring of the fetal heart rate, uterine contractions, fetal movements, and serial urinary estriol determinations may also be useful in diagnosing and managing such complex cas-s

The association of human fetal respiration with the fetal heart rate was studied in 13 pregnant patients between Weeks 34 and 41 of pregnancy. Fetal respiration was recorded with the use of a tocodynamometer. Fetal heart rate was recorded with the use of ultrasound and abdominal fetal electrocardiogram monitoring devices. The results documented the presence of human fetal respiratory arrhythmia. An increase in fetal heart rate was seen during fetal 'inspiration' followed by a decrease during 'expiration.' The possible mechanisms of the respiratory arrhythmia are discussed

A study of fetal activity was undertaken as the first step in a series of physiologic fetal movement studies. A simple, safe, noninvasive, clinically applicable method for studying fetal movement with a tocodynamometer is described. Four basic types of fetal movement have been seen and defined in terms of their durations, recorded patterns, and descriptive terminologies for identifying each movement

The influence of balanced anesthesia (BA) on fetal heart rate (FHR) and uterine contraction (UC) patterns was evaluated in pregnant women undergoing emergency cesarean section. The results showed that during operative delivery under BA there was a significant decrease in the beat-to-beat variability of the FHR, most probably due to the anesthetic agent. There was a decrease in uterine contractility expressed by the significant decreases in the peak pressure as well as in the duration of the uterine contractions. Periodic changes in the FHR as decelerations and acclerations disappeared or improved mostly due to the decrease of uterine contractility

A rare complication of ovulation induction with clomiphene citrate is presented. The importance of keeping in mind such a serious complication is emphasized in order to achieve early diagnosis and appropriate management. In pregnancies following clomiphene treatment, close supervision is imperative as soon as pregnancy is evident

A study of 257 operative culdoscopies done without general anaesthesia is presented and the advantages and limitations of the technique are detailed

A case of unruptured Ampullary pregnancy in the 7th postmenstrual week is presented, which was diagnosed and treated at the same time by operative culdoscopy. The indication and advantages of this method are discussed
