为了诊断的目的,常分析桡动脉脉搏记录。这种分析可用于诊断血管疾病。最近提出的压力的时间微商可能是心脏喷射动作和瓣膜功能的灵敏指标。Starr及其同事用电子学方法使压力波微分,但这种办法增加了噪声水平。作者运用换能器和有关电学方法,能够在相当小的噪声情况下对高频成分进行观察。仪器情况已另有报导。我们从一组伸舌样迟钝病对象取得的数据,可以作为本设计的临床评价的一部分。此数据与从同一医院的另一组病人得到的数 Radial artery pulse records are often analyzed for diagnostic purposes. This analysis can be used to diagnose vascular disease. The recently proposed stress time derivative may be a sensitive indicator of cardiac ejection motion and valve function. Starr and his colleagues electronically differentiate pressure waves, but this approach adds noise levels. Using transducers and electrical methods, the authors are able to observe the high-frequency components with relatively little noise. The condition of the instrument has been reported otherwise. The data we obtained from a group of dumb-like subjects can be part of the clinical evaluation of this design. This figure is the same as the number of patients from another group in the same hospital
