Abstract
The efficacy of cardiac resynchronization therapy applied to a patient's heart by an implantable device are improved by obtaining acute hemodynamic feedback during implantation of a pacing device. A first and a second transducer are temporarily placed proximate to a portion of the patient's heart during device implant, and a distance between the transducers is monitored as the therapy is applied. A parameter (e.g. lead location, biventricular pacing, pacing rate, or the like) of the cardiac therapy is adjusted in response to the distance between the transducers until a desired result is obtained, after which the first and second transducers can be removed from the patient.
