Insights

Paediatric atrial fibrillation (AF) is rare in children without congenital heart disease. Evaluation for underlying cardiac issues, like cardiomyopathy, is crucial for managing this arrhythmia and preventing complications such as thromboembolism.

Area of Science:

  • Pediatric Cardiology
  • Cardiac Electrophysiology
  • Arrhythmology

Background:

  • Paediatric atrial fibrillation (AF) is uncommon, typically occurring without congenital heart disease.
  • Children usually lack the myocardial structural and functional changes that sustain arrhythmias.
  • Presentation necessitates evaluation for occult cardiac pathologies, including cardiomyopathy and inherited arrhythmia syndromes.

Purpose of the Study:

  • To review the evaluation and management of paediatric atrial fibrillation.
  • To highlight potential underlying causes and associated risks.
  • To discuss complications and treatment strategies for paediatric AF.

Main Methods:

  • Literature review of paediatric atrial fibrillation cases.
  • Analysis of diagnostic approaches for identifying underlying cardiac conditions.
  • Review of management strategies, including cardioversion and anticoagulation.

Main Results:

  • Haemodynamically unstable patients with AF require synchronized cardioversion.
  • Stable patients should be managed in consultation with a paediatric cardiologist.
  • Sustained AF can lead to tachycardia-induced cardiomyopathy and thromboembolism, often necessitating anticoagulation.

Conclusions:

  • Paediatric AF warrants thorough investigation for concealed cardiac pathology.
  • Risk factors include increasing age, body mass index, obesity, and athletics.
  • Recurrence is possible even without identified underlying pathology, emphasizing ongoing monitoring.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Disturbances in Heart Rhythm

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.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
