The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This study is an observational study designed to determine the extent of gastrointestinal (GI) post-procedure complications after Radiofrequency Catheter Ablation (RFCA) for atrial fibrillation (AF). This exploratory study will evaluate patient symptoms prior to the RFCA procedure, at 1 month post RFCA procedure, and at 3 months post RFCA procedure, through the administration of a questionnaire. The purpose of this study is to determine if vagus nerve injury resulting from RFCA for AF increases the risk of post-procedure GI complications that may present as temporary or permanent symptoms.
Symptoms Associated with Vagus Nerve Injury [ Time Frame: At RFCA procedure, 1 month post RFCA procedure, 3 months post RFCA procedure ]
The composite of symptoms associated with vagus nerve injury: increased heart rate, bloating, early satiety, heartburn, changes in bowel habits, weight loss, problems with swallowing, nausea and vomiting. These symptoms will be discovered through the administration of a questionnaire.
