Objective To determine the electrocardiographic performance and Results Breech presentation occurred in 750 of 23 219 (3.2%) neonatal outcome of pregnancies with breech presentation and deliveries, 625 (83%) of which were selected for vaginal delivery. planned vaginal delivery monitored with ST-waveform analysis Intrapartum monitoring by STAN was performed in 433 (69%). (STAN). Compared with vertex presentations, fetuses in breech presentation had a lower risk of baseline T/QRS rise during Design Prospective observational study. labour [odds ratio (OR) = 0.7, 95% confidence interval (95% Setting University hospital, Norway; 2004–2008. CI) = 0.7–0.9, P = 0.003] and a higher risk for intervention as a result of preterminal cardiotocogram (OR = 2.9, 95% CI = 1.6– Population Singleton pregnancies with a gestational age above 5.9, P = 0.001).
