Objective: Atrial fibrillation (atrial fibrillation, atrial fibrillation, AF) is the most common clinical arrhythmia. In recent years, the catheter ablation of atrial fibrillation great strides, has become the first-line treatment experienced centers. With the continuous promotion of the treatment and its associated complications are also increasingly attention, which gradually attracted the attention of the majority of scholars ablation-related complications in the digestive system. Digestive complications vagus nerve damage around the esophagus, gastrointestinal disorders, paralytic ileus, gastroparesis, and phrenic nerve damage, mainly to delayed gastric emptying. There is currently a lack of research on the incidence of such complications, and prognosis system. Through the study of changes in the atrial fibrillation before and after radiofrequency ablation of gastric emptying time, this study further reveals the treatment of the digestive system, and to provide further guidance for clinical work. METHODS: March 2010 to December 2010 in our hospital, 16 patients with paroxysmal atrial fibrillation, inclusion criteria: anti-arrhythmic drugs (including: metoprolol, bisoprolol, propafenone hydrochloride Cho) and diltiazem hydrochloride ineffective treatment, symptoms, agree to the treatment of patients with atrial fibrillation catheter ablation. Exclusion criteria: hyperthyroidism, caused by rheumatic heart disease, pulmonary heart disease, myocardial infarction, atrial fibrillation and left atrial thrombus formation in patients, as well as to accept the second radiofrequency catheter ablation patients. Selected patients with a history of 1 to 10 years (mean 2.75 ± 0.72), aged 42 to 76 years (mean 56.31 ± 2.46), including 10 men and two cases of patients with hypertension, one cases of patients with chronic superficial gastritis, and the rest patients found no organic disease, gastrointestinal barium meal perspective, observed preoperative, postoperative gastric emptying time change. Results: All 16 patients with paroxysmal atrial fibrillation radiofrequency ablation were in sinus rhythm after surgery, no postoperative complications. No significant change in the 16 patients ablation postoperative gastric emptying time than ablation. Surgical ablation in patients, including 11 cases of circumferential pulmonary vein ablation increased atrial ablation lesions in other parts of the remaining patients. The results suggest that the most obvious left atrial lesion area patients, postoperative gastric emptying time delay is relatively obvious, macrocyclic ablation of circumferential pulmonary vein the surgery left room at the top of the left atrial isthmus coronary sinus superior vena cava ablation of patients with delayed gastric emptying , but because of the small number of cases and is not used for statistical analysis of whether there are differences. Conclusion: This study showed that radiofrequency ablation-difference, will lead to a different dynamic effects of surgery-related gastrointestinal ablation range and digestive system damage is relatively light; positive preventive measures, including perioperative application of gastric mucosal protective agent, promote motility drugs and antacids and other drugs may reduce the degree of change in the gastrointestinal tract dynamics.
