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.
