Proper management of cattle reproduction has a major impact on the efficiency and profitability of dairy production. Ultrasound examination and transrectal palpation or the pregnancy-associated glycoprotein (PAG) test are currently the most commonly used methods for pregnancy diagnosis. However, alternative methods to those mentioned above are constantly being sought in order to minimise stress during the examination, the cost of veterinary services and to reduce the rate of errors in pregnancy diagnosis.

To investigate the correlation between fetoplacental circulation and maternal left ventricular myocardial work (MW) parameters in patients with preeclampsia (PE) and the prediction of fetal hypoxia. Seventy-eight PE patients (PE group) were assigned to intrauterine-hypoxia (27) and non-intrauterine-hypoxia (51) groups, and 45 healthy pregnant women were controls. The receiver operating characteristic (ROC) curve evaluated the diagnostic efficacy of each parameter for fetal intrauterine hypoxia.

A 35-year-old pregnant woman was referred to our hospital because of fetal bradycardia. Fetal echocardiography revealed a normal fetal heart except for slightly prominent trabeculae in the left ventricle, normal cardiac function, and fetal sinus bradycardia with a heart rate of 100 bpm. Electrocardiography (ECG) after birth revealed sinus bradycardia with a heart rate of 70-80 bpm.

Identifying and understanding prenatal developmental disorders at an early stage are crucial as fetal brain development has long-term effects on an individual's life. The maturation of the fetal autonomic nervous system (ANS) is believed to influence the coordination and direction of maternal-fetal heartbeat synchronization. Fetal behavioral states (FBSes) include quiet sleep (1F), active sleep (2F), quiet awake (3F), and active awake (4F).

Article Synopsis
- Premature ventricular beats during pregnancy can lead to serious complications like palpitations, reduced placental blood flow, and risks for the fetus, including miscarriage.
- A case study highlights the successful use of radiofrequency catheter ablation on a pregnant woman with a rare focus of these beats, demonstrating both the challenges and positive outcomes of the procedure.
- The use of fluoroscopy-less ablation is beneficial as it minimizes radiation exposure while ensuring a high success rate and safety for pregnant patients.
