Insights

This study presents a novel approach combining left bundle branch area pacing with defibrillation support for a patient with heart failure and ventricular tachycardia. This innovative technique aims to prevent cardiac death and improve ventricular function by mitigating pacing-induced dyssynchrony.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Device Technology

Background:

  • Heart failure with reduced ejection fraction (HFrEF) poses significant risks, including sudden cardiac death from ventricular arrhythmias.
  • Conventional right ventricular pacing can exacerbate left ventricular dysfunction in HFrEF patients.
  • Biventricular pacing is recommended for HFrEF with conduction disorders but may induce dyssynchrony in patients with narrow QRS.

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...

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...
