Article Title: Estimation of Respiratory Frequency in Women and Men by Kubios HRV Software Using the Polar H10 or Movesense Medical ECG Sensor during an Exercise Ramp
doi: 10.3390/s22197156
Figure Lengend Snippet: Respiratory frequency (RF) plotted over time for Movesense Medical sensor ECG (MS ECG), Polar H10 (H10) (Kubios window width: 30 s, grid interval: 1 s) and the gas exchange data (GE) in four representative participants. ( A ): 26-year-old female with a BMI of 30 kg/m², VO 2MAX of 38 mL/kg/min, Kubios artifact rate of 0.5%; ( B ): 27-year-old female with a BMI of 22 kg/m², VO 2MAX of 42 mL/kg/min, Kubios artifact rate of 0.0%; ( C ): 47-year-old male with a BMI of 38 kg/m², VO 2MAX of 31 mL/kg/min, Kubios artifact rate of 0.0%; ( D ): 25-year-old female with a BMI of 21 kg/m², VO 2MAX of 40 mL/kg/min, Kubios HRV artifact rate of 0.7%. MS ECG (red circle), H10 (blue circle), GE (black). Ramp termination corresponds with peak GE respiratory rate. Length of post ramp recovery determined by data recording cessation and artifacts below 3%.
Article Snippet: Recordings of RR intervals and ECG were taken continuously with two devices at the same time, the Movesense Medical sensor (firmware version 2.0.99) single-channel ECG with chest belt (Movesense, Vantaa, Finland; sampling rate: 512 Hz; app software: Movesense Showcase version 1.0.9), and the Polar H10 sensor chest belt device (Polar Electro Oy, Kempele, Finland; sampling rate: 1000 Hz; app software: Elite HRV App, Version 5.5.1).
