TH and atrial fibrillation: After transfection with lncRNA TCONS_00202959 overexpressing lentivirus, atrial effective refractory period in AF rats was prolonged, AF inducibility was decreased, autonomic nerve function was significantly improved, and TH levels were decreased, indicating that lncRNA TCONS_00202959 may inhibit the occurrence and development of AF by improving cardiac autonomic nerve function.
