Patient's question:
My colleague has heart disease and underwent catheter ablation for atrial fibrillation. It has been a year since the surgery. Will he have a recurrence after the surgery? What should he pay attention to? I would like to ask a few questions. Will there be a recurrence after catheter ablation?Doctor's answer:
Will there be a relapse after radiofrequency ablation? This is not certain. It is necessary to go to the hospital for follow-up examination in a timely manner. Atrial fibrillation has degenerative inflammation in the elderly heart. Due to fibrosis and other reasons, the function of the sinoatrial node, the heart's natural pacemaker, may atrophy and cannot generate normal electrical signals. It can only be replaced by many surrounding ectopic sites with potential pacemaker functions.Relapse can occur after radiofrequency ablation. Paroxysmal supraventricular tachycardia is a diagnosis of a group of diseases, the most common of which are preexcitation syndrome and congenital multiple accessory pathways in the heart, which lead to tachycardia. This can be diagnosed through an electrocardiogram during the onset.
