Why the study?
Because cardiac communication with central autonomic circuits is impaired in AF, it was hypothesized that heartbeat-evoked potentials reflecting cardiac signaling to central autonomic areas are attenuated in these patients.
Is the heartbeat-evoked potential (HEP) attenuated in patients with persistent atrial fibrillation compared to matched controls?

Attenuated HEP in AF may indicate impaired heart-brain signaling; hypothesis-generating and requires prospective validation before any clinical use.
Is the heartbeat-evoked potential (HEP) attenuated in patients with persistent atrial fibrillation compared to matched controls?
Patients with persistent atrial fibrillation exhibit attenuated heartbeat-evoked potentials, particularly in the right insula, suggesting impaired heart-brain interoceptive signaling.
