Evaluating Infrasonic Hemodynography
Evaluating Infrasonic Hemodynography
This comparative diagnostic accuracy study will determine the accuracy of a noninvasive
 wearable infrasonic sensor to detect the mechanical, electrical, and hemodynamic function of
 the cardiovascular system.
This comparative diagnostic accuracy study will determine the accuracy of a noninvasive
 wearable infrasonic sensor to detect the mechanical, electrical, and hemodynamic function of
 the cardiovascular system. 25 patients with cardiovascular disease will undergo a
 comprehensive echocardiogram, electrocardiogram, and cardiac catheterization while wearing a
 infrasonic earbud device. The infrasonic and hemodynamic waveforms will be analyzed using
 machine learning with the goal of correlating infrasound data captured by the earbud to the
 patient's cardiovascular hemodynamics.
