Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
