Summary
Neonatal atrial tachycardia, including focal atrial tachycardia and atrial flutter, is common. Diagnosis and treatment are key, with most neonates having an excellent prognosis and rare recurrence of atrial flutter.
Area of Science:
- Pediatric Cardiology
- Neonatal Electrophysiology
Background:
- Atrial tachycardia (AT) is a frequent arrhythmia in neonates.
- Focal AT and atrial flutter are common types of AT in newborns.
- Accurate diagnosis and management of neonatal arrhythmias are crucial skills.
Purpose of the Study:
- To guide clinicians in diagnosing and treating neonatal atrial tachycardia.
- To differentiate between mechanisms of focal AT and atrial flutter.
- To provide counseling on therapy for neonatal arrhythmias.
Main Methods:
- Review of current literature on neonatal atrial tachycardia.
- Analysis of diagnostic criteria for focal AT and atrial flutter.
- Guidance on therapeutic approaches and long-term management.
Main Results:
- Most neonates with atrial tachycardia have an excellent prognosis.
- Atrial flutter recurrence is rare after successful termination.
- Focal AT often requires treatment but may be discontinued later in childhood.
Conclusions:
- Effective management of neonatal atrial tachycardia requires understanding its mechanisms.
- Therapy for focal AT can often be discontinued as the child matures.
- Clinicians need to be proficient in managing these arrhythmias in newborn patients.

01:29Dysrhythmias III: Characteristics of Dysrhythmias
404
Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per...

479
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

01:17Increased pulse rate
1.1K
Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues.
Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...

01:29Disturbances in Heart Rhythm
2.5K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.

484
Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

2.5K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
