Abstract

BACKGROUND: By using the conventional method of measuring two-points (systolic and diastolic) blood pressure, it is difficult to differentiate a heart disease-prone personality from normals. Recently, an oscillometric method that reflects the personalized trait of blood pressure was developed by one author.

OBJECTIVE: By using this new measurement technique, this study intended to test the possibility of differentiating a heart disease-prone personality (type A or type D) from normal people.

METHODS: TPA scale in MMPI-2 and DS14 were used for screening type A and D. Oscillometric waveforms created by the cuff pressure were segmented into window blocks based on a single beat at a minimum, allowing this method to extract maximal top and bottom amplitudes in each window block. Then, a spectrogram using a short-time Fourier transform was applied to discriminate between character types in extracted blood pressure patterns with linear discriminant analysis.

RESULTS: Compared to a normal personality, type A and type D personalities displayed a lower frequency response on STFT with maximum negative amplitudes than normals. In particular, the type D personality showed a lower frequency response than the type A personality.

CONCLUSION: These results could provide a new qualitative method for measuring different biological indices between type A or D personalities and normals.
