Systems and methods for cardiac pacing using beta blockers

A system for determining pacing attributes for a patient, the system comprising:

• a memory configured to store processor-readable instructions;
• and
• one or more processors operatively connected to the memory, and configured to execute the instructions to perform operations that include:
• receiving a beta blocker use signal;
• determining use of a beta blocker with intrinsic sympathomimetic activity (ISA) by the patient based on the beta blocker use signal;
• receiving a current physiological input;
• and
• determining pacing attributes based on the determining use of the beta blocker with ISA and the current physiological input.

A method for determining pacing attributes for a patient, the method comprising:

• receiving a current physiological input;
• determining pacing attributes based on the current physiological input;
• causing a pacing device to output pacing outputs based on the pacing attributes;
• receiving an updated physiological input after causing the pacing device to output the pacing outputs;
• determining that a difference between the current physiological input and the updated physiological input does not meet a threshold difference;
• and
• generating an indication of a presence or use of a non-intrinsic sympathomimetic activity (non-ISA) beta blocker based on the difference not meeting the threshold difference.
