Disturbances in Heart Rhythm

950
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...

Summary
This summary is machine-generated.

Prophylactic ventricular tachycardia ablation improves outcomes in ischemic heart disease. Novel imaging and ablation technologies enhance targeting and long-term success for ventricular tachycardia (VT) ablation.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Technology

Background:

  • Ischemic heart disease is a leading cause of ventricular tachycardia (VT).
  • Current clinical practice for VT management has limitations.
  • Improving procedural and long-term outcomes for VT ablation is crucial.

Purpose of the Study:

  • Evaluate current evidence on ventricular tachycardia ablation in ischemic heart disease.
  • Explore novel approaches to enhance VT ablation outcomes.
  • Assess the role of advanced imaging and mapping in VT ablation.

Main Methods:

  • Review of recent clinical trials (PARTITA, PAUSE-SCD, SURVIVE-VT).
  • Analysis of advanced cardiac imaging for substrate evaluation.
  • Evaluation of advanced cardiac mapping techniques.
