The Frequency Analysis and the Atrial Fibrillation

The Frequency Analysis and the Atrial Fibrillation

Atrial fibrillation (AF) is the most common cardiac arrhythmia in clinical practice. It is well known that AF depends on the interaction between the “triggers” and “substrate”, and the elimination or isolation of the “trigger” can cure AF. In recent years, growing knowledge of atrial substrate mapping has helped in learning more about the maintenance of AF, and to identify the critical atrial substrate for catheter ablation, in spite of the elimination of all triggers initiating AF.
