Summary
This study introduces arrayed pulse wave analysis to objectively measure Traditional Chinese Medicine (TCM) pulse characteristics, identifying specific array pulse volume (APV) indicators for hypertensive vascular function.
Area of Science:
- Integrative Medicine and Biomedical Engineering
- Cardiovascular Diagnostics
- Traditional Chinese Medicine (TCM) Research
Background:
- Traditional pulse diagnosis in TCM offers rich information but lacks objective quantification.
- Existing single-point instruments capture limited pulse wave data.
- Sensor arrays offer multipoint, multiparameter signal acquisition, simulating a doctor's touch.
Purpose of the Study:
- To develop methods for analyzing arrayed pulse wave signals.
- To apply these methods to identify objective indicators of hypertensive disorders.
- To validate the use of sensor arrays for TCM pulse characteristic analysis.
Main Methods:
- Acquired pulse wave signals from the left 'guan' location using a sensor array.
- Calculated average pulse wave (APW) and identified the most representative pulse wave (MRPW).
- Analyzed array pulse volume (APV) parameters and compared between healthy and hypertensive groups using t-tests and Mann-Whitney U tests.
Main Results:
- Significant elevations in multiple APV parameters were observed in the radial, intermediate, and ulnar passages of hypertensive individuals compared to healthy controls.
- Specific APV parameters (e.g., RP APV, IP APV, UP APV) showed statistically significant differences (P < 0.01 or P < 0.05).
- The study validated arrayed pulse wave analysis as a method to reliably reflect TCM pulse characteristics.
Conclusions:
- Arrayed pulse wave analysis provides a novel, objective approach to quantifying TCM pulse information.
- Identified specific APV parameters as effective indicators of hypertensive vascular function.
- Sensor arrays enhance the ability to capture multidimensional information inherent in TCM pulses.

1.2K
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.

01:17Pulse amplitude and quality
2.3K
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

1.7K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
