Evaluating Infrasonic Hemodynography

Clinical Correlation of a Novel Wearable Sensor to Detect Cardiovascular Mechanical and Electrical Properties Through 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.
