R-Wave Detection
In order to detect a heartbeat, a heart monitor looks for R waves; the detected beat is
annunciated and used for rate calculations and other analysis. By adjusting the R wave,
the range of settings can be determined for which a given heart monitor will detect a beat.
The MPS450 simulates an R wave that is adjustable to a wide range of preconfigured
settings for rate, width, and amplitude.
Setting R-Wave Rate
The MPS450 offers six preconfigured settings (BPM) for R-wave rate: 30, 60, 80, 120,
200, or 250.
