Article Synopsis
  • Macroreentry is the main cause of typical and atypical flutter, but many questions about it remain unanswered, prompting a study that uses topology to investigate atrial tachycardia activation patterns.
  • Researchers utilized a computational model resembling a closed sphere with holes to analyze cases of tachycardia, focusing on activation maps and ablation responses in 131 clinical cases.
  • The study's findings suggest that reentrant activity on closed surfaces consistently shows paired rotation, and through mathematical principles, they established a framework to better understand flutter and its treatment outcomes.

Cardiac fibrosis stands as one of the most critical conditions leading to lethal cardiac arrhythmias. Identifying the precise location of cardiac fibrosis is crucial for planning clinical interventions in patients with various forms of ventricular and atrial arrhythmias. As fibrosis impedes and alters the path of electrical waves, detecting fibrosis in the heart can be achieved through analyzing electrical signals recorded from its surface.

Cardiac arrhythmias such as atrial fibrillation (AF) are recognised to be associated with re-entry or rotors. A rotor is a wave of excitation in the cardiac tissue that wraps around its refractory tail, causing faster-than-normal periodic excitation. The detection of rotor centres is of crucial importance in guiding ablation strategies for the treatment of arrhythmia.
