Description
Compare a pulse inter-beat interval with a supplied reference interval.
Physiological signals have explicit sampling intervals, polarity, time origins and cycle conventions. One cycle period differs from a robust averaged rate, and wrapped external-clock phase differs from measured biological phase. Supplied markers and gas-reference labels organize data without detecting events or establishing normal physiology.
Compare a pulse inter-beat interval with a supplied reference interval.
When to use this tool
Use Pulse Inter Beat Time Residual when you already have observedIntervalMilliseconds, referenceIntervalMilliseconds and need to compare a pulse inter-beat interval with a supplied reference interval.
How to use the tool and how it works
- Enter observedIntervalMilliseconds, referenceIntervalMilliseconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read residualMilliseconds. Use the output convention below.
Require both intervals>0 in ms; return observed-reference milliseconds.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| observedIntervalMilliseconds | Observed Interval Milliseconds | Required. Finite number; strictly above 0. |
| referenceIntervalMilliseconds | Reference Interval Milliseconds | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| residualMilliseconds | Residual Milliseconds | Required. Finite number. |

}Limitations and assumptions
- No signal, rhythm, heart rate variability or clinical abnormality is evaluated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect the original signal, event markers and acquisition clock when deriving physiological quantities. Use an appropriate multi-cycle or time-varying analysis when a single supplied interval, fixed sampling rate or wrapped external-time phase is insufficient.
