Synchronous analysis of ECG & PPG

3

If we have 2 (or more) signals, it will be good to analyze them in join. For example, if we have 1 or more ECGs + 1 or more PPGs,...

PPG_findpeaks detection failure with single spike artifact

4

If PPG contains just a single (but big) spike, the ppg_findpeaks returns only single value: that spike position. The problem is in the threshold calculation algorithm: thr1 = ma_beat +...
