Holter Monitor: 24-Hour Monitoring

3
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...

Pulse rhythm01:30

Pulse rhythm

768
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...

Area of Science:

  • Neurology
  • Biomedical Engineering
  • Medical Technology

Background:

  • Epilepsy seizure detection is critical for patient safety and quality of life.
  • Wearable sensors have limitations, including patient tolerance and practicality for newborns.
  • Non-contact video and audio-based seizure detection methods are emerging but lack comprehensive review.

Purpose of the Study:

  • To provide a scoping literature review of video and audio-based seizure detection technologies.
  • To summarize existing methods, performance, benefits, and challenges.
  • To identify research gaps and inform future advancements in non-contact seizure detection.

Main Methods:

  • Conducted a scoping literature review across 7 databases.
  • Screened 4,487 deduplicated abstracts, selecting 34 relevant studies.
  • Analyzed diverse study designs, algorithms, seizure types, and performance metrics.

Main Results:

  • Seizure detection sensitivity varied widely (0% to 100%), with optical flow analysis showing the highest sensitivity.
  • Specificity ranged from 60% to 97.7%.
  • The highest reported accuracy was 100% using a Radon Transform technique.

Conclusions:

  • Video and audio-based tools offer promising non-contact seizure detection and monitoring.
  • Current studies are limited by small sample sizes, dataset diversity, and lack of standardized evaluation.
  • Future research requires larger, diverse datasets and standardized protocols for generalizable results.
