Pulse rate variability compared with Heart Rate Variability in children with and without sleep disordered breathing
Summary
Pulse rate variability (PRV) accurately estimates heart rate variability (HRV) in children using time-domain analysis. However, PRV is less precise for frequency-domain HRV parameters, especially in children with sleep disordered breathing (SDB).
Area of Science:
- Cardiology
- Biomedical Engineering
- Pediatric Sleep Medicine
Background:
- Heart Rate Variability (HRV) quantifies autonomic activity using electrocardiogram (ECG) R-R intervals.
- Photoplethysmography (PPG) signals offer a non-invasive alternative for heart rate monitoring.
- Assessing Pulse Rate Variability (PRV) as an HRV surrogate in pediatric populations is crucial.
Purpose of the Study:
- To evaluate the accuracy of PRV derived from PPG as an estimate of HRV in children.
- To compare PRV and HRV in children with and without sleep disordered breathing (SDB).
- To assess the reliability of time-domain and frequency-domain HRV/PRV parameters.
Main Methods:
- Simultaneous ECG and PPG recordings were obtained from 72 children using a mobile phone-connected oximeter.
- Polysomnography was used as the gold standard for data acquisition.
- Correlation and Bland-Altman analyses compared HRV and PRV metrics (SDNN, RMSSD, LF/HF ratio).
Main Results:
- High correlation (r > 0.90) and agreement were observed between HRV and PRV for mean intervals, SDNN, and RMSSD.
- Significant divergence was noted for the LF/HF ratio between HRV and PRV.
- Children with SDB exhibited lower SDNN/RMSSD and higher LF/HF ratios compared to controls.
Conclusions:
- PRV is a valid and accurate surrogate for time-domain HRV analysis in children.
- PRV demonstrates limitations in precisely estimating frequency-domain HRV parameters, particularly the LF/HF ratio.
- PRV can be a valuable tool for assessing autonomic function in pediatric research and clinical settings, especially when ECG is unavailable.

2.0K
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...

Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.

1.7K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
