Insights

Congenital isolated atrio-ventricular block (CAVB) is rare, but patients show good long-term survival. Early diagnosis, especially in utero, indicates a worse prognosis for children with CAVB.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Congenital Heart Disease

Context:

  • Congenital isolated atrio-ventricular block (CAVB) management is poorly described in literature.
  • A retrospective study analyzed 30 cases of isolated congenital CAVB from 1980-2003.
  • The average follow-up period was 14 years, with no reported deaths.

Purpose:

  • To describe the management and long-term outcomes of congenital isolated atrio-ventricular block (CAVB) in pediatric patients.
  • To evaluate the effectiveness of cardiac stimulation in managing CAVB.
  • To identify factors influencing prognosis in CAVB.

Summary:

  • Thirty patients with isolated congenital CAVB were studied, with 20 requiring pacemakers due to symptoms or bradycardia.
  • Epicardial VVI pacing was the initial approach in 65% of cases, followed by endocavitary pacing in 81%.
  • Cardiac stimulation did not prevent dilated cardiomyopathy; 10 patients without pacemakers experienced chronotropic insufficiency during exertion.

Impact:

  • Patients with CAVB demonstrate a favorable long-term vital prognosis.
  • CAVB diagnosed in utero is associated with a poorer prognosis for affected children.
  • This study contributes valuable data on the long-term management and outcomes of congenital CAVB.

Conduction System of the Heart01:19

Conduction System of the Heart

Autorhythmicity is a term that refers to the heart's inherent ability to generate electrical signals and instigate muscle contractions. This self-regulating conduction system within the heart consists of two key components: the pacemaker cells and specialized conducting cells.
The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...

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...
Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

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...

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...
