1. A method, comprising:

  • sensing, during an event of tachycardia, concurrently by at least two different types of sensors at least two different types of hemodynamic signals, wherein the at least two different types of sensors are located at at least two spatially separated locations within a patient;

    quantifying a spatial relationship between the sensed at least two different types of hemodynamic signals;

    determining a state of patient hemodynamics during the tachycardia event based at least in part on the quantified spatial relationship;

    selecting one or more anti-tachycardia therapies to treat the tachycardia based at least in part on the determined state of patient hemodynamics; and

    delivering the selected one or more anti-tachycardia therapies to treat the tachycardia.
