Beat-to-beat blood pressure variability and heart rate variability in relation to autonomic dysregulation in patients with acute mild-moderate ischemic stroke.

•Autonomic dysregulation is underdiagnosed in this population due to a lack of simpler diagnostic tools.•To correlate beat-to-beat BPV and HRV with Ewing’s test classification.•Autonomic dysregulation is associated with lower variation of blood pressure and heart rate in acute ischemic stroke.•Non-invasive monitoring of beat-to-beat BPV and HRV may be an alternative to autonomic dysregulation measure.•In clinic, we may use the cut-off values of LF/HF RRI, LF/HF dBP and LF/HF sBP for diagnosis of autonomic dysfunction.
