摘要：
A novel non-interfering scheme for recording vascular dynamics and inferring cardiovascular conditions is presented. The method exploits bioimpedance in 50 kHz to 1 MHz range. A carefully designed electrode configuration, filtering and validation scheme allows for localized measurements of distension, pulse wave velocity and pulse shape. Pulse pressure can be inferred from these quantities and with knowledge about the arterial stress-strain relation also the absolute pressure can be determined.
