Getting log from unity and ECG physiological markers using VB script

Hello all, I'm doing a project for my masters, where we use unity for VR, and we want to have people to be in the trial and experience this VR space and be connected to ECG, for reading their heart beat as a physiological marker. My questions are thus, 1. Does anyone knows of such a pipeline of unity and external machine like ECG or EEG, and what logs can I get? (it's a tough one, not sure I understand it myself) 2. Can I record the trial using a plugin maybe, so all the time the user in the VR, his trial is recorded and I can watch it latter on. EDIT: Does anyone knows if I can integrate VBscript API's with UNITY3D? Thanks!
