Abstract
Electrocardiogram, Ballisto cardiogram, brachial arterial blood pressure wave and the femoral arterial blood pressure wave were sumultaneously recorded on 15 healthy adult males for comparative study.
1) In the femoral arterial blood pressure wave, time lags were observed in each point of the wave form. The time lag at the peak and at the dicrotic elevation is larger than that at the peak and at the initial ascending point of the wave form.
2) As to the absolute values, the values measured in the femoral arterial blood pressure wave form were generally higher than those recorded in the other wave forms.
3) The femoral arterial blood pressure waves demonstrated roughly common wave form, while the brachial arterial blood pressure waves showed various different wave forms.
