Pulse Spectrum Analysis in Primary Hypertension Patients
摘要
Background and Purpose: Arterial pulse diagnosis is noninvasive and it is very popular in traditional Chinese medicine clinics. The aim of this study was to evaluate the possibility of using pulse diagnosis in patients with the primary hypertension. Methods: Noninvasive analyses of radial pulses were taken in primary hypertension patients immediately after their arrival at the physical examination room. They then underwent physical health examinations including measurement of blood pressure and heart rate, EKG, blood test, urine test, x-ray, ultrasound scanning, and recording medical history. We carried out pulse spectrum analysis on 110 patients with possible primary hypertension. We used five criteria for pulse diagnosis of blood pressure abnormalities to test for correlation. These were (1) C1≧2 (in intensity) and C4≦-3 (in intensity) or C4≦-2 (in phase), (2) C0≧4 (in intensity) and C4≦-2 (in intensity), (3) C0≧4 (in intensity) and C3≦-2 (in intensity) and C3≦-2 (in phase), (4) C0≧4 (in intensity) and C3≦-2 (in intensity) and C5≦-3 (in intensity), (5) C3≦-2 (in intensity and phase) and C6≦-2 (in intensity and phase). For the intensity, C1 (liver) every 5% above normal was given one ”+”, every 5% below normal was given one ”-”. For C3 (spleen), C4 (lung), C6 (gallbladder), every 10% above normal was given one ”+”, every 10% below normal was given one ”-”. For the phase, every 10% delay in the traveling speed of the pressure wave was given one ”-”. Results: Only the ”+”, ”N” (N = normal) and ”-” states were considered, while quantities of ”+” ”-” were not monitored. In the pulse analysis, there were 311 (from intensity) × 311 (from phase) = 177, 147 × 177, 147 possible states (3 qualitative states and 11 harmonics). We considered only five criteria for blood pressure abnormalities and the correlation was very high, p＜0.001, Kappa = 0.701. Conclusion: The results strongly suggested that each harmonic of pulse spectrum has physiological and pathological importance in
