P02.96. Effects of deep breathing on pulse pressure harmonics
نویسندگان
چکیده
Purpose Pulse pressure waveforms can be decomposed into individual harmonics using frequency-domain analyses. Based on the well-recognized phenomenon of pulse wave reflections, these harmonics are purported to play important physiological functions and form the basis for Traditional Chinese Medicine (TCM) pulse diagnosis. Although breathing is considered an essential part of TCM and Qi Gong, its effects on pulsatile hemodynamics are unknown. This study explored the effects of slow, deep breathing on blood pressure harmonics.
