Holter Monitor: 24-Hour Monitoring01:23

Holter Monitor: 24-Hour Monitoring

101
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

874
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...

Factors Influencing Heart Rate01:30

Factors Influencing Heart Rate

3.0K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Correlation between ECG and Cardiac Cycle01:25

Correlation between ECG and Cardiac Cycle

7.6K
The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

Area of Science:

  • Equine cardiology
  • Biomedical engineering
  • Veterinary diagnostics

Background:

  • Electrocardiograms (ECGs), heart rate (HR), and heart rate variability (HRV) are crucial for equine cardiovascular assessment.
  • Smart textiles offer potential for non-invasive physiological monitoring, but require validation in equine applications.

Purpose of the Study:

  • To compare HR and HRV data from a smart textile system (Myant) against a gold-standard telemetric device (Televet) in horses.
  • To evaluate the reliability of smart textiles for equine cardiovascular monitoring during rest and exercise.

Main Methods:

  • Simultaneous ECG recordings were obtained from seven horses at rest and during submaximal exercise using both Myant and Televet systems.
  • Bland-Altman analysis was employed to assess agreement between the two devices for HR and HRV parameters (SDRR, TI).

Main Results:

  • Strong to perfect correlations were observed between the smart textile system and the gold-standard device for all assessed metrics.
  • HR (r = 0.9993) and HRV parameters (SDRR r = 0.8765, TI r = 0.8712) showed very strong correlations.
  • Minimal biases were found for HR, SDRR, and TI during exercise, indicating good agreement.

Conclusions:

  • The smart textile system demonstrates high reliability and accuracy for measuring equine HR and HRV.
  • This technology is suitable for monitoring horse cardiovascular health and fitness at rest and during exercise.
