ObjectiveTo examine the effect of time after birth on heart rate (HR) measured by pulse oximetry (PO) (HRPO) and electrocardiography (ECG) (HRECG).Study designHRECG and HRPO (collected at maximum sensitivity) were assessed in 53 term and preterm infants at birth. ECG electrodes and a PO sensor were attached as soon as possible and HRECG and HRPO were compared every 30Â seconds from 1-10Â minutes after birth. Data were compared using a Wilkinson signed-rank test. Clinical relevance (eg, HRÂ <100 beats per minute [bpm] was tested using a McNemar test).ResultsSeven hundred fifty-five data pairs were analyzed. Median (IQR) gestational age was 37 (31-39) weeks. Mean (SD) starting time of PO and ECG data collection was 99 (33) vs 82 (26) seconds after birth (PÂ =Â .001). In the first 2Â minutes after birth, HRPO was significantly lower compared with HRECG (94 (67-144) vs 150 (91-153) bpm at 60Â seconds (PÂ <Â .05), 81 (60-109) vs 148 (83-170) bpm at 90Â seconds (PÂ <Â .001) and 83 (67-145) vs 158 (119-176) at 120Â seconds (PÂ <Â .001). A HRÂ <100 bpm was more frequently observed with a PO than ECG in the first 2Â minutes (64% vs 27% at 60Â seconds (P = .05), 56% vs 26% at 90Â seconds (PÂ <Â .05) and 53% vs 21% at 120Â seconds (PÂ <Â .05). HR by ECG was verified by ultrasound for outflow from a subset of infants.ConclusionsIn infants at birth, HRPO is significantly lower compared with ECG with clinically important differences in the first minutes.
