Final answer:
Bradycardia is a condition where the resting heart rate drops below 60 bpm. In infants or children, if they still have a pulse but it is super bradycardic (<60), it may indicate insufficient oxygenated blood to the tissues. Causes of bradycardia include abnormalities in the SA or AV node, heart muscle ischemia, diseases of the heart vessels or valves, metabolic and endocrine disorders, neurological disorders, drug use, or prolonged bed rest.
Step-by-step explanation:
Bradycardia is a condition where the resting heart rate drops below 60 bpm. In infants or children, if they still have a pulse but it is super bradycardic (<60), it may indicate that the heart is not providing sufficient oxygenated blood to the tissues. While bradycardia may be inherited or acquired, it can be caused by abnormalities in the SA or AV node, ischemia to the heart muscle, diseases of the heart vessels or valves, metabolic disorders, endocrine disorders, neurological disorders, over-prescription of certain drugs, recreational drug use, or prolonged bed rest. Treatment would depend on identifying the underlying cause and may involve the use of a pacemaker or supplemental oxygen.
