“…Theories developed in animal models were not tested in humans and showed no theoretical correspondence with TCM [21,22]. Findings from healthy participants could not be extrapolated to other populations without proper evidence [23e25], and incomplete descriptions of the diagnostic criteria for hypertension, as well as traditional descriptions of PIA, were also found [24,26]. Finally, a lack of comparison among patterns of hypertension was found [26].…”

Hypertension affects functional capacity and quality of life. Pulse wave analysis (PWA) quantifies the pulse waveform's propagation and its changes resulting from arterial remodeling. Pulse image analysis (PIA) in traditional Chinese medicine contributes to pattern differentiation and therapeutic intervention. This protocol study evaluates the relationships between the parameters of both PWA and PIA to identify patterns in patients with hypertension and the associations of those patterns with functional capacity. In this observational, cross-sectional study protocol 40 patients were subjected to clinical and laboratorial examinations to assess the risk factors for cardiovascular disease and pattern differentiation. PWA was noninvasively performed at the radial artery to estimate the pulse wave's velocity, arterial compliance, and reflection index. PIA using the "simultaneous pressing" method was performed to assess nine indicators. Handgrip strength and physical activity was assessed as functional outcomes. We hypothesized that interactions between patterns and pulse images affect the PWA parameters and that the functional outcomes are weakly associated with personal, hemodynamic and risk factors for cardiovascular disease. Performing a PIA in patients with hypertension might allow the identification of early target-organ damage, standardization of the PIA based on the PWA, and unification of the pulse diagnosis.

Pulse diagnosis is one of the efficient techniques to detect the health status of a patient. However, pulse diagnosis suffers from a viewpoint of nonscientific and subjectivity. The goal of this report wants to propose an outline to integrate both the quantification of pulse diagnosis and application of clinic. Hence, the definitions of the quantifiable parameter are followed by clinical experiences. These core parameters are classified into four categories: position, rate and rhythm, shape, and trend. Using Bi-Sensing Pulse Diagnosis Instrument (BSPDI) to acquire wrist artery information for interpreting pulse conditions. The DS (Depth-Strength) curve can be classified the pulse condition whether it belongs to floating pulse or sunken pulse; and similarly, DR (Depth-Rate-Rhythm) curve to rapid pulse or slow pulse, DW (Depth-Width) curve to fine pulse or large pulse, DL (Depth-Length) curve to long pulse or short pulse. The pulse conditions will be understood based on these curves and pulse diagnosis is no more subjectivity and nonscientific.

“…Luo et al designed a bi-sensing pulse diagnosis instrument (BSPDI) using strain gauges and a pressure sensor array [10]. Three strain gauges (each for each finger) are used to measure the depth of each finger pushing onto the patient's wrist, while the pressure sensor array is used to obtain the wrist pulses.…”

Abstract-Major applications of sensor technologies in cardiovascular disease (CVD) diagnoses include (1) detect heart pulse waveforms, (2) measure blood properties, (3) create heart or vessel images, and (4) establish wireless CVD detecting or monitoring network. Sensors such as piezoresistive and strain gauge sensors have been used to automatize or modernize TCPD; conductive, impedance, and optical sensors have been utilized to obtain ECG, ICG, and PPG waveforms, respectively, to assess the patient's cardiovascular status; piezoelectric sensors are used in ultrasound devices to generate a moving picture of the heart, show its size, shape, structure, and how well its valves are working; piezoelectric sensors, as well as electromagnetic and capacitive sensors can also be used to detect and record the sounds from the heart or blood flow in arteries and veins. Radiation sensors detect penetrated X-ray to create CCT images; inductive sensors (coils) can pick up 10-100MHz radio waves released from soft tissues after their H-atoms' magnetic resonance and create a cardiac MRI.
