- Abstract:
- A low-cost wearable system has been developed, that was used to record simultaneously the electrocardiographic signal (ECG) and photoplethysmographic signal (PPG).The prototype permits an offline working mode, being capable of recording both signals, ECG and PPG, on a memory card, using Arduinonano board. The recorded signals consist from the first derivation of ECG and the PPG signal collected from the left-hand index finger. First, we collected signals from several subject, in the same manner for all, before detecting the interested peaks from those signals, we removed the noise, from ECG to avoid false or missed peaks that can appear during the recording process, and we determined the RR peaks and R-to-R time interval. Also from PPG signal, we determined the PP peaks and P-to-P time interval. Using these results we determined the differences (ε) between the R-to-R and P-to-P time intervals, in order to observe which is the greatest difference between these parameters and if we can replace the RR intervals with PP interval. From the obtained results, we concluded that the majority of the differences are lower than 3%, about 92% from the total of the detected intervals. Also we detected that 5% of the differences are between 3% and 5%, and only 3% are above 5%.
