Systems, devices, and methods for health monitoring via implantable devices in the anterior mediastinum

A method of using an implanted ambulatory system for health monitoring, the method comprising:

• receiving electrical signal data from an electrical sensor disposed in an anterior mediastinum of a patient, the electrical sensor configured to detect electrical signals radiating from an external surface of a heart;
• receiving pressure signal data from a pressure sensor disposed in the anterior mediastinum of a patient, the pressure sensor configured to detect a pressure signal in the anterior mediastinum;
• determining, based on the electrical signal data and the pressure signal data, at least one cardiac parameter;
• monitoring the at least one cardiac parameter over a period of time to determine if a change in the cardiac parameter has occurred;
• and
• executing, in response to determining that the change in the cardiac parameter has occurred, at least one action associated with the change.

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to:

• receive electrical signal data from an electrical sensor disposed in an anterior mediastinum of a patient, the electrical sensor configured to detect electrical signals radiating from an external surface of a heart;
• receive pressure signal data from a pressure sensor disposed in the anterior mediastinum of a patient, the pressure sensor configured to detect a pressure signal in the anterior mediastinum;
• define a hemodynamic curve based on a first portion of the pressure signal data in a first frequency band and a pulmonary curve based on a second portion of the pressure signal data in a second frequency band different from the first frequency band;
• and
• monitor at least one cardiac parameter over a period of time based at least in part on changes in the electrical signal data, the hemodynamic curve, and the pulmonary curve.

• receiving pressure signal data from a pressure sensor disposed in the anterior mediastinum, the pressure sensor configured to detect pressure signals in the anterior mediastinum;
• amplifying and filtering the pressure signal data to define a hemodynamic curve corresponding to pressure signals in a first frequency band and a pulmonary curve corresponding to pressure signals in a second frequency band different from the first frequency band;
• defining a change in a health status of the patient over a period of time based on (i) the electrical signal data, the hemodynamic curve, and the pulmonary curve and (ii) a change in at least one of the electrical signal data, the hemodynamic curve, or the pulmonary curve over the period of time;
• and
• executing at least one action associated with the change in the health status.
