Systems, devices, and methods for improving patient outcomes in implantable cardioverter defibrillators

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:

• determine an electrical status of a heart of a patient based on a first signal received from an electrical sensor of an ICD lead that has been implanted in an anterior mediastinum of a patient, the electrical sensor configured to detect electrical signals radiating from the heart;
• calculate a hemodynamic output of the heart based on a second signal received from a pressure sensor of the ICD lead, the pressure sensor configured to detect pressure changes in the anterior mediastinum due to a mechanical functioning of the heart;
• and
• define, based on a correlation between the electrical status and the hemodynamic output of the heart, a treatment decision associated with delivering a shock treatment to the heart.

A system, comprising:

• an electrical sensor coupled to a lead configured to be implanted in an anterior mediastinum of a patient, the electrical sensor configured to detect electrical signals radiating from a heart of the patient;
• a pressure sensor coupled to the lead, the pressure sensor configured to detect pressure changes in the anterior mediastinum due to a mechanical functioning of the heart;
• and
• an implantable cardioverter defibrillator (ICD) configured to be implanted in the patient, the ICD including a generator coupled to the lead when the lead is implanted in the anterior mediastinum, the generator including a memory and a processor configured to execute instructions stored in the memory operable to cause the processor to:
• determine an electrical status based on a first signal received from the electrical sensor;
• calculate a hemodynamic output of the heart based on a second signal received from the pressure sensor;
• and
• define, based on a correlation between the electrical status and the hemodynamic output of the heart a treatment decision associated with delivering a shock treatment to the heart.

A method for improving treatment decisions of an implantable cardioverter defibrillator (ICD) implanted in a patient, comprising:

• determining an electrical status based on a first signal received from an electrical sensor of an ICD lead implanted in an anterior mediastinum of a patient, the electrical sensor configured to detect electrical signals radiating from a heart of the patient;
• determining a hemodynamic output of the heart based on a second signal received from a pressure sensor coupled to the ICD lead, the pressure sensor configured to detect pressure changes in the anterior mediastinum due to a mechanical functioning of the heart;
• and
• responsive to each of the electrical status and the hemodynamic output being associated with a cardiac arrhythmia, causing a generator of the ICD to generate a shock treatment energy to be delivered via the ICD lead to the heart of the patient.
