Data quality assessment of a simultaneous catheter and MindMics IH time series for b left and c right earbuds data shown for each cardiac cycle in an exemplary 30-s study subject’s data. Cardiac cycles are defined by times between two consecutive QRS peaks of the ECG tracing (vertical lines). The distribution of signal quality, assessed using cross-correlation scores, is shown for d catheter waveforms, e IH signals from the left earbud, and f IH signals from the right earbud. Shaded regions indicate waveforms that passed the quality threshold.
