Abstract：
UNASSIGNED: To examine speed and accuracy of newborn heart rate measurement by various assessment methods employed at birth.
UNASSIGNED: A search of Medline, SCOPUS, CINAHL and Cochrane was conducted between January 1, 1946, to until August 16, 2023. (CRD 42021283364) Study selection was based on predetermined criteria. Reviewers independently extracted data, appraised risk of bias and assessed certainty of evidence.
UNASSIGNED: Pulse oximetry is slower and less precise than ECG for heart rate assessment. Both auscultation and palpation are imprecise for heart rate assessment. Other devices such as digital stethoscope, Doppler ultrasound, an ECG device using dry electrodes incorporated in a belt, photoplethysmography and electromyography are studied in small numbers of newborns and data are not available for extremely preterm or bradycardic newborns receiving resuscitation. Digital stethoscope is fast and accurate. Doppler ultrasound and dry electrode ECG in a belt are fast, accurate and precise when compared to conventional ECG with gel adhesive electrodes.
UNASSIGNED: Certainty of evidence was low or very low for most comparisons.
UNASSIGNED: If resources permit, ECG should be used for fast and accurate heart rate assessment at birth. Pulse oximetry and auscultation may be reasonable alternatives but have limitations. Digital stethoscope, doppler ultrasound and dry electrode ECG show promise but need further study.

摘要：
■通过出生时采用的各种评估方法检查新生儿心率测量的速度和准确性。
■搜索Medline，Scopus,CINAHL和Cochrane于1946年1月1日至2023年8月16日进行。(CRD42021283364)研究选择基于预定标准。审稿人独立提取数据,评估偏倚风险并评估证据的确定性。
■在心率评估方面，脉搏血氧定量比ECG慢且精确度低。听诊和触诊对于心率评估都不精确。其他设备，如数字听诊器，多普勒超声,一种心电图装置，其使用的干电极结合在皮带上，在少数新生儿中研究了光电体积描记术和肌电图，并且没有接受复苏的极早产或心动过缓新生儿的数据。数字听诊器是快速和准确的。皮带中的多普勒超声和干电极心电图速度快，准确和精确相比，传统的心电图与凝胶粘合电极。
■对于大多数比较，证据的确定性很低或很低。
■如果资源允许，应在出生时使用ECG进行快速准确的心率评估。脉搏血氧饱和度和听诊可能是合理的选择，但有局限性。数字听诊器,多普勒超声和干电极心电图显示出希望，但需要进一步研究。
