Problems solved by technology
The success rate of this method cannot be replicated by other centers at present, that is, the clinical real success rate is low. The main defect is that the electrode density is too low, and the resolution of the collected signal is not enough to truly present the essence of rotor electrical activity, resulting in a false positive rate. higher

The invention discloses a method and system for recognizing an atrial fibrillation rotor site. The method comprises the following steps: S1, acquiring a first preset number* M endocardium bipolar electric signals and a second preset number* N endocardium bipolar electric signals from a database, wherein M and N are positive integers; S2, determining the average perimeter of atrial fibrillation according to the second preset number* N endocardium bipolar electric signals; and S3, carrying out dispersion analysis on the first preset number* M endocardium bipolar electric signals according to theaverage perimeter of the atrial fibrillation, and recognizing the atrial fibrillation rotor site. The method has the beneficial effects that the atrial fibrillation rotor site is accurately recognized from a first preset number of sites by a dispersion analysis method, false-positive rotor sites are reduced, an accurate target spot is provided for guidance of atrial fibrillation radiofrequency ablation, and iatrogenic injury caused by excessive ablation is relieved.
Description
technical field [0001] The invention relates to the technical field of atrial fibrillation, in particular to a method and system for identifying a trochanteric site of atrial fibrillation. Background technique [0002] In 1998, French scientists first proposed the theory of pulmonary vein origin of atrial fibrillation, revealing that paroxysmal atrial fibrillation is triggered by pulmonary veins, and ablation of pulmonary vein ectopic excitation can achieve the purpose of treating paroxysmal atrial fibrillation. However, this theory completely ignores the maintenance mechanism of atrial fibrillation. Moreover, catheter ablation only electrically isolates the triggering mechanism of pulmonary veins, and does not intervene in the maintenance mechanism of atrial fibrillation, resulting in the recurrence rate of paroxysmal atrial fibrillation remaining at about 30%. In recent years, the rotor phenomenon proposed by Dr. Narayan in the United States can drive the existence of atr...
