Episode: Tricks to Get Better HRV and ECG Signal Quality - How Electrode Placement, Shirt Material, Impedance Affect ECG and HRV Data – José Näf (Pt2)
Description: Does clothing material affect ECG signal quality?
José Näf explains how electrostatic effects, electrode placement, and connector design influence long-term HRV and ECG data accuracy.
In this second episode, Dr. Olli Tikkanen continues his discussion with José Näf, co-founder of Nahtlos, diving deeper into the practical challenges of long-term ECG and HRV monitoring. José shares critical insights on how connector types, electrode placement, and impedance changes over time affect signal quality.
From the role of electrostatic interference caused by clothing materials to the importance of correct electrode positioning along the heart’s axis, t...
