Bradycardia in neonates is defined as a heart rate of:

Bradycardia in neonates is defined as a heart rate of less than 60 beats per minute. This threshold is critical because it signifies a potential compromise in the oxygen supply to vital organs, which can lead to serious complications if not addressed promptly. In neonates, a heart rate below the defined range indicates the need for immediate assessment and intervention.

The heart rate in newborns typically ranges from 120 to 160 beats per minute when they are at rest. Understanding this normative data is vital for recognizing deviations from expected patterns. A heart rate that drops below the established threshold signifies the need for medical evaluation, potential resuscitation measures, and monitoring, as bradycardia can be symptomatic of underlying health issues such as respiratory distress or central nervous system problems.

It's important to note that while the other options present heart rates above 60 beats per minute, they do not align with the clinical definition of bradycardia in this patient population. This highlights the importance of recognizing the correct parameters for assessing bradycardia in neonates to ensure timely and appropriate medical responses.
