This measurement allows the recording of the pulse pressure at two different sites of the aorta and the measurement of the distance between the two pressure waves (Figure 1). The former is usually ...

Healthy hearts are adaptable, and heartbeats exhibit complex variation as they adjust to tiny changes in the body and ...

Pulse compression uses a long transmission that varies in frequency. Reflected waves can be reconstituted to act more like a short pulse since there is information about the exact timing of the ...

It works in the same way as sonar but with radio waves in place of ultrasound. A short pulse of radio waves is transmitted and the time it takes for the reflection (the echo) to return is measured.

People may feel a pulse in their abdominal aorta, a large artery that runs through the stomach area. People may feel pulsing in the stomach during pregnancy or when pressing on the abdomen.
