Non-invasive prognostic biomarker of lung cancer patients with brain metastases: Recurrence quantification analysis of heart rate variability

open access: yesFrontiers in Physiology, 2022
Background: It has previously been shown that the time-domain characteristic of heart rate variability (HRV) is an independent prognostic factor for lung cancer patients with brain metastasis (LCBM).

RQA differences among states are robust to parameter choice.

open access: yes, 2023
A RQA metrics for different tolerance levels ϵ defining recurrence in phase space. We vary ϵ from 0 std to 4 std of the population firing counts. Setting ϵ to 0 means that a recurrence occurs between two times for the exact same neuronal firing pattern ...
