The heartbeat evoked potential, a brain signal reflecting heart-brain communication, has been proposed as a biomarker for various health conditions. However, a comprehensive meta-analysis finds too much methodological inconsistency across studies to draw firm conclusions about its clinical utility.
The heartbeat evoked potential (HEP) is an electrophysiological indicator of cortical processing of cardiac signals and a putative neural index of cardiac interoception. Various clinical conditions…
