Inclusion criteria
Inclusion criteria: Study Group: 1. Age = 18 years, no restriction on gender; 2. Successfully completed atrial fibrillation catheter ablation; 3. At screening, a 12-lead ECG showing sinus rhythm meeting the diagnostic criteria for interatrial conduction block, excluding P wave widening caused by other reasons. Control Group: 1. Age = 18 years, no restriction on gender; 2. Successfully completed atrial fibrillation catheter ablation; 3. At screening, ECG confirmed sinus rhythm (heart rate 60-100 beats per minute).
Exclusion criteria
Exclusion criteria: Exclusion criteria for the study group: 1. Valvular AF, such as after mechanical valve replacement or moderate to severe rheumatic mitral stenosis; 2. Combined with other known diseases that can cause cardiovascular adverse events (such as hyperthyroidism, history of cardiac surgery, etc.); 3. History of radiofrequency catheter ablation for all types of atrial arrhythmias and left atrial appendage closure surgery; 4. Patients with cardiac pacemaker implantation; 5. Presence of other causes leading to P wave widening: (1) Significant enlargement of the left atrium/right atrium (echocardiographic left atrial anterior-posterior diameter >= 50 mm or right atrial transverse diameter >= 45 mm); (2) Electrolyte disorders (serum potassium 5.5 mmol/L); (3) Uncontrolled hyperthyroidism or hypothyroidism; (4) Taking drugs affecting atrial conduction (such as amiodarone, propafenone, sotalol, etc., with a discontinuation time of < 5 half-lives). Exclusion criteria for the control group: 1. Valvular AF, such as after mechanical valve replacement or moderate to severe rheumatic mitral stenosis; 2. Combined with other known diseases that can cause cardiovascular adverse events (such as hyperthyroidism, history of cardiac surgery, etc.); 3. History of radiofrequency catheter ablation for all types of atrial arrhythmias and left atrial appendage closure surgery; 4. Patients with cardiac pacemaker implantation.
