Fifty eight gravidas near-term underwent external cephalic version using tocolytic treatment and continuous fetal monitoring by cardiotocograph and real-time ultrasound. No unfavorable maternal or fetal effects were recorded. Fetal heart rates showed a significant decline at 10 and 30 min after the procedure with complete recovery at 1 h after external version, but no pathologic tracing was recorded. No uniform heart rate patterns due to external cephalic version could be found.
