What is the leading cause of bradycardia in pediatric patients?

Bradycardia Causes The most common cause of bradycardia in children and teenagers is sinus bradycardia. This simply means that the sinus node is firing at a slow rate.

What is bradycardia in an infant?

Bradycardia is a slowing of the heart rate, usually to less than 80 beats per minute for a premature baby. Bradycardia often follows apnea or periods of very shallow breathing. Sometimes it is due to a reflex, especially with the placing of a feeding tube or when the baby is trying to have a stool.

What are some 4 systemic presentations of bradycardia?

Bradycardia can be physiologic, pathologic, or pharmacologic in origin. Alteration of either the sinoatrial (SA) or atrioventricular (AV) conduction system may play a role. Symptoms of bradyarrhythmias include fatigue, dizziness or syncope, and dyspnea and angina.

What is the most likely cause of bradycardia?

Bradycardia can be caused by:

Heart tissue damage related to aging.
Damage to heart tissues from heart disease or heart attack.
Heart disorder present at birth (congenital heart defect)
Infection of heart tissue (myocarditis)
A complication of heart surgery.
Underactive thyroid gland (hypothyroidism)

What heart rate is considered bradycardia in children?

For the purpose of this topic review, we define bradycardia as a heart rate measured in the awake state that is below the normal range for age (ie, <100 beats per minute [bpm] for infants, <80 bpm for toddlers and young children, <70 for school age children, and <60 for adolescents).

What Causes bradycardia in a child?

Common causes of sinus bradycardia in children include increased vagal tone, hypothyroidism, hypothermia, adrenal insufficiency, and increased intracranial pressure. Inherited arrhythmias and cardiomyopathies may also cause bradycardia.

What are the signs and symptoms of a symptomatic bradycardia?

If you have bradycardia, your brain and other organs might not get enough oxygen, possibly causing these symptoms:

Near-fainting or fainting (syncope)
Dizziness or lightheadedness.
Fatigue.
Shortness of breath.
Chest pains.
Confusion or memory problems.
Easily tiring during physical activity.

When does bradycardia need to be treated?

Patients with imminent heart failure or unstable patients with bradycardia need immediate treatment. The drug of choice is usually atropine 0.5–1.0 mg given intravenously at intervals of 3 to 5 minutes, up to a dose of 0.04 mg/kg. Other emergency drugs that may be given include adrenaline (epinephrine) and dopamine.

What is the prognosis of bradycardia?

Prognosis. Bradycardia may be an acute or chronic problem depending upon the etiology. It may resolve and never recur if the inciting event is treated or removed (e.g., hypothyroidism, electrolyte derangements, or medications). However, for patients with an underlying conduction system disease,…

What is the differential diagnosis of bradycardia?

Bradycardia: Differential Diagnosis General Notes: The younger the patient the higher the resting pulse generally is. A pulse of < 60 bpm is considered bradycardia in adults, whereas in newborns a pulse < 60 bpm with evidence of low perfusion considered a reflection of a life

Is bradycardia considered heart failure?

Bradycardia has many causes such as drug abuse, thyroid dysfunction, dehydration, infections, neurological problems and heart disease. According to “Harrison’s Principles of Internal Medicine ,” the most common heart disease that leads to bradycardia is congestive heart failure.

What causes bradycardia and tachycardia?

Tachycardia can be caused by congenital abnormalities, heart disease, and some types of lung diseases. It can also be caused by substance abuse and a reaction to some medications. Causes of bradycardia include electrolyte imbalances, hypothyroidism, and blood pressure medication side effects.

What is the leading cause of bradycardia in pediatric patients? Bradycardia Causes The most common cause of bradycardia in children and teenagers is sinus bradycardia.
