Sentence examples for successive differences in from inspiring English sources

For HRV, the ln 5-min standard deviation of the normal-to-normal (NN) interval (LnSDNN) and the ln root mean square of successive differences in adjacent NN intervals (LnRMSSD) were positively associated with the PM2.5 mass concentration (p < 0.05).

The first term is corresponding to the data-fidelity term, and the last two terms aim to ensure the sparsity in both x and their successive differences in x.

Vagal tone is assessed by the root mean square of successive differences in these interbeat intervals (RMSSD), that has previously been proven to be a valid index of vagal tone.

Heart rate and two heart rate variability measures (the SD of all filtered RR intervals over the length of the recording (SDNN) and the root mean square of successive differences in normal RR intervals (rMSSD)).

Heart rate variability, including standard deviation of RR intervals (SDNN), root mean square of successive differences in RR intervals (RMSSD), and frequency domain parameters (low frequency/high frequency) will also be calculated.Heart rate turbulence comprising turbulence onset and slope as well as acceleration and deceleration capacity will be computed.

We performed a cross-sectional analysis of 23 urinary metals and 5-min HRV indices (SDNN, standard deviation of normal-to-normal intervals; r-MSSD, root mean square of successive differences in adjacent normal-to-normal intervals; LF, low frequency; HF, high frequency; TP, total power) using baseline data on 2,004 adult residents of Wuhan.

HRV was measured as the root mean square of successive differences (RMSSD) in the IBIs (Camm et al., 1996).

c) variability in the time series using the root mean squares of successive differences (RMSSD), which describes the difference in successive activity counts from minute to minute.

Root mean square of successive differences.

An example is the mean square successive differences (MSSD), which implies the average of the squared difference between successive observations.

In general, short-term HRV rMSSD (root mean square of successive difference) reflects alterations in autonomic tone that are predominantly vagally mediated (Kleiger et al. 1995).
