Summary
Continuous monitoring of high-frequency heart rate variability (HF-HRV) using ECG devices is feasible in at-risk adolescents. This method provides reliable data for approximately three weeks, even during sleep and school days.
Area of Science:
- Cardiology
- Adolescent Health
- Mental Health Research
Background:
- Suicide risk in adolescents is a significant public health concern.
- Objective physiological markers for monitoring at-risk youth are needed.
- Continuous ambulatory monitoring offers potential for improved assessment.
Purpose of the Study:
- To assess the feasibility of continuous ambulatory high-frequency heart rate variability (HF-HRV) monitoring in high-risk adolescents.
- To evaluate data quality and compliance rates for this monitoring method.
Main Methods:
- Utilized chest-worn electrocardiogram (ECG) devices for continuous HF-HRV monitoring.
- Included adolescents identified as at high risk for suicide.
- Data collection occurred over approximately two to three weeks, encompassing daily life activities.
Main Results:
- The monitoring met pre-defined feasibility benchmarks, achieving ≥75% compliance.
- High data quality was maintained throughout the monitoring period.
- Feasibility was demonstrated across diverse conditions, including school days and sleep.
Conclusions:
- Continuous ambulatory HF-HRV monitoring via ECG is a feasible and high-quality method for assessing at-risk adolescents.
- This technology can provide valuable physiological data for understanding and potentially intervening in adolescent suicide risk.
- Further research should explore the clinical utility of this monitoring approach.

01:30Pulse rhythm
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 muscle...

01:23Holter Monitor: 24-Hour Monitoring
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...
