ABSTRACT
The beginnings of noninvasive arterial pulse recording can be traced to the Renaissance. At that time, the Polish scientist, Strus (1555) had proposed that the arterial pulse possesses a waveform. Although instrumentation that he used was simple, he suggested that changes in the arterial pulse shape and strength may be related to disease conditions. Today, even though the technology is more advanced, noninvasive arterial blood pressure measurement still remains a challenge. Rigorous methods for extracting functional cardiovascular information from noninvasive pressure have been limited.
