Systems and methods for automated localization of wearable cardiac monitoring systems and sensor position-independent hemodynamic inference

A wearable cardiac monitoring system comprising:

• a motion sensor configured to detect movement of a user's chest and output seismocardiographic data;
• and
• a non-transitory, computer-readable medium having instructions stored thereon that, when executed by one or more processors, cause a controller to:
• receive the seismocardiographic data from the motion sensor;
• determine, based at least in part on the seismocardiographic data, a classifier of the seismocardiographic data;
• determine, based at least in part on the seismocardiographic data, a signal quality index of the seismocardiographic data;
• determine, based on the classifier and the signal quality index, a quality of the seismocardiographic data;
• and
• output, to a graphical user interface, an indication of the quality of the seismocardiographic data.
