Figure Lengend Snippet: Recovery of PPG signals through motion artefact reduction (MAR) and synchronizing these PPG signals with Polar (ECG). ( a ) Recovering PPG with reference motion; ( b ) Synchronization between recovered PPG and golden standard ECG.

Article Snippet: HR was simultaneously monitored with a Polar Bluetooth® Smart chest strap ECG device, an accessory to Polar’s Bluetooth® Smart wGT3X-BT activity monitor (Acti-Graph, LLC, Pensacola, FL, USA) as well as Mio-Alpha (Physical Enterprises Inc., Vancouver, BC, Canada) wrist watch HR monitor as the references.

Figure Lengend Snippet: Electrocardiogram from calreticulin transgenic mice. (a) Representative traces of electrocardiogram from transgenic and control mice of different ages. (b) Heart rates of nonsedated transgenic (M148) and control mice. The number of measurements is indicated inside the bar. AP < 0.001. (d) Progressive AV node disease: from 11-day-old heart (upper recording) to 18-day-old heart (middle recording) to sudden death (lower recording) (20-day-old heart). P, P wave indicating atrial activation; QRS, QRS complex indicating ventricular activation; P-R interval, time of onset of P wave to onset of QRS interval.

Article Snippet: ECG Leads I, II, III, AVR, and AVL of nonsedated transgenic and control mice from the age of 4 days until death were simultaneously recorded using E for M ECG amplifiers (PPG Biomedical Systems Inc.; Pleasantville, New York, USA).

Article Title: Cerebral pulsatility might be a driver of neurofunctional reorganization in the aging brain: an MRI and NIRS study

doi: 10.3389/fnagi.2025.1486775

Figure Lengend Snippet: (A) Example of simultaneous ECG, and raw NIRS intensity data (830 nm) for a few seconds in a participant’s channel. The cerebral pulse amplitude (CPA) is defined as the amplitude from the systolic peak to the diastolic peak, baseline-corrected to the systolic peak in the NIRS data. (B) NIRS source and detector arrangement plotted on cortex. The arrangement is symmetric for the right and left hemispheres. Red circles indicate sources, blue circles represent far-channel detectors, and yellow circles denote short-channel detectors. (C) Schema of the color-word interference Stroop task diagram. Trials were displayed in French: rouge [red], bleue [blue], jaune [yellow], and verte [green].

Article Snippet: NIRS recordings were conducted simultaneously using ECG (BIOPAC BSL PRO MP36U-W, BIOPAC Systems, Inc., Goleta, CA, United States) with a sampling rate of 1,000 Hz ( ).

Figure Lengend Snippet: Bland–Altman plots and scatter plots of heart rate (HR) obtained by RGB sensor and electrocardiogram (ECG) or pulse oximeter. ( a ) Bland–Altman plot of raw green trace method applying FFT. ( b ) Bland–Altman plot of the proposed method applying tapered window, signal reconstruction and MUSIC. ( c ) Scatter plot of raw green trace. ( d ) Scatter plot of proposed method.

Article Snippet: Their RR, HR and body temperature were measured using the contactless system; reference measurements were simultaneously obtained using a contact-type electrocardiogram (ECG) (LRR-03, GMS Co. Ltd., Tokyo, Japan) or pulse oximeter (SAT-2200 Oxypal mini, NIHONKOHDEN Co., Tokyo, Japan), clinical thermometer (TERUMO electric thermometer C230, TERUMO Co., Tokyo, Japan) and a respiration effort belt (DL-231, S&ME Inc.,Tokyo, Japan).
