Demonstrable by the electrophysiological methods, smoking has a direct effect on fetal cardiac function. The fetal heart rate variability shows a pattern during smoking which is a typical sign of stress conditions among adults. The results may have educational consequences as well. Understanding those, hopefully will help pregnant women give up this harmful addiction.

Objective. The aim of the study was to develop a complex electrophysiological measurement system (hardware and software) which uses the methods of electrophysiology and provides significant information about the intrauterine status of the fetus, intending to obtain true-to-form, morphologically evaluated fetal ECG from transabdominal maternal lead. Results. The present method contains many novel ideas that allow creating true-to-form noninvasive fetal ECG in the third trimester of the pregnancy in 80% of the cases. Such ideas are the telemetric data collection, the “cleanse” of the real time recording from the maternal ECG, and the use of the cardiotocograph (CTG) that allows identifying the fetal heart events. The advantage of this developed system is that it does not require any qualified staff, because both the extraction of the information from the abdominal recording and the processing of the data are automatic. Discussion. Although the idea of a noninvasive fetal electrocardiography is more than 100 years old still there is no simple, effective, and cheap method available that would enable an extensive use. This developed system can be used in the third trimester of the pregnancy efficiently. It can produce true-to-form fetal ECGs with amplitude less than 10 µV.

showed in the ultrasound a heterogeneous endometrium with 17 mm thick without identification of any embryonic structures and no fluid in the Douglas' pouch. A week later her ␤-hCG in the serum was of 4177 mUI/mL and the pelvic ultrasound shows an image within the fundus/left horn compatible with an ectopic pregnancy. The patient was submitted to diagnostic laparoscopy followed by left cornual resection and left salpingectomy by laparotomy. Histological studies of the fragment showed signs of decidualization and tissue invasion by trophoblast. 2. 27 year old woman, G4P1 (cesarean section in 2014), sent by the Reproductive Health Consult with the diagnosis of ectopic pregnancy. The ultrasoud showed near the left horn of the uterus a econegative image with peripheral vasculature and deciduous reaction with about 31 mm × 23 mm. Conclusion: The described clinical cases were treated surgically, reducing the likelihood of relapse, and both cases had only as risk factor a history of previous pelvic surgery. None of the patients had acute abdominal hemorrhage or was ever hemodynamically unstable.
