An electrode for introduction through the abdominal wall of a pregnant woman or animal for monitoring the fetal heart is described which includes an elongated rod having at one end a handle for rotating the rod about its longitudinal axis, and a helical electrode tip portion at the other end of the rod which is pointed to penetrate through the abdominal wall as the rod is rotated. The rod is designed with a length sufficient to extend through the abdominal section and uterine wall as the rod is rotated such that the electrode tip portion will hook onto the fetus skin and thereby pick up the fetus cardiogram. A flexible plastic shroud is attached near the electrode handle and encircles the electrode rod with adhesive means on one end of the shroud for securing to the abdominal skin around the area where the electrode enters the abdomen. The plastic shroud prevents foreign particles and germs from entering the opening while the electrode is in place, thereby maintaining a sterile environment. After fetal monitoring, an electrode jack connector is unplugged from the back of the electrode handle, the rod and electrode tip portion backed off from the fetus by reverse rotation, and the shroud removed.
