The Difference Between Sampled IBI and Live IBI Data

Jan 29, 2019

In the exported data, there are different types of IBIs (interbeat intervals): Live IBI's and Sampled IBI's
  • Sampled IBI's are a series of 4-byte integers, sampled every 500 milliseconds.  The number of items is exactly twice the minute duration.
  • Live IBI's are a series of 4-byte integers, at one value for each pulse/IBI.  The pulse start time would be the time that the pulse wave was drawn.
