title: [The relationship between intrapartum fetal heart rate disturbances, electrocardiographic changes and umbilical venous troponin-I (T-I)].
abstract: OBJECTIVE
  To analyse the relationship between intrapartum fetal heart rate disturbances and electrocardiographic changes and umbilical venous troponin-I (T-I), concentrations as well.
  
  
  METHODS
  14 fetuses were continuously surveyed by CTG and ECG recordings in the first and second stage of labor, using STAN S-21 analyser. After birth, umbilical venous blood samples were collected for determination of acid-base balance, base excess and troponin-I concentrations.
  
  
  RESULTS
  From among monitored fetuses, in 8 cases the CTG and FECG patterns were correct. Vaginally delivered neonates were born in good clinical status, with normal acid-base balance, base excess and T-I < 0.3 ng/ml. In 3 cases abnormal CTG patterns were observed with early decelerations but FECG patterns were correct. Vaginally delivered neonates were born in good clinical status, with normal acid-base balance, base excess and T-I < 0.3 ng/ml. In 2 cases abnormal CTG patterns were observed with variable decelerations but FECG patterns were correct. Vaginally delivered neonates were born in good clinical status, with normal acid-base balance, base excess and T-I < 0.3 ng/ml. In one case abnormal CTG pattern were observed with late decelerations but FECG patterns was correct. The pregnancy was terminated by caesarean section because of fetal distress. The neonate was born in good clinical status with normal acid-base balance and base excess but T-I concentration was increased (1.5 ng/ml).
