Summary
This study improved a pulse transducer to stably record carotid artery pulse (CAP) during exercise. The new method captures exercise-induced CAP changes on bicycle ergometers up to 160 beats/min.
Area of Science:
- Cardiovascular Physiology
- Biomedical Engineering
- Exercise Science
Background:
- Continuous and stable recording of carotid artery pulse (CAP) during exercise is challenging.
- Previous methods lacked the stability and continuous monitoring required for exercise studies.
Purpose of the Study:
- To improve a fixing apparatus for pulse transducers.
- To enable continuous and stable recording of CAP during bicycle ergometer exercise.
Main Methods:
- Development and application of an improved fixing apparatus for pulse transducers.
- Recording CAP during supine and upright bicycle ergometer exercise.
- Analysis of CAP waveform changes during exercise onset, oscillation, and cessation.
Main Results:
- The improved apparatus allowed continuous and stable CAP recording during exercise.
- Significant changes in CAP were observed at exercise onset and cessation.
- CAP contour differed during exercise, with lower incisura and occasional tidal wave dominance.
- The method was effective for heart rates below approximately 160 beats/min.
Conclusions:
- The improved fixing apparatus enables reliable CAP monitoring during exercise.
- Exercise significantly alters CAP morphology, providing insights into cardiovascular responses.
- This technique is valuable for studying exercise hemodynamics in various ergometer positions.
