Methods and apparatus for determining cardiac stimulation sites using hemodynamic data
First Claim
1. A method of implanting a stimulation electrode within the heart of a patient, comprising:
- (a) positioning the stimulation electrode at a test location in the heart of a patient;
(b) delivering electrical energy to the location;
(c) determining a first acute hemodynamic response in reaction to the electrical energy delivered to the location;
(d) assessing whether the first acute hemodynamic response is satisfactory;
(e) repeating steps (a) through (d) until the first acute hemodynamic response at the test location is satisfactory;
(f) delivering electrical energy to the test location;
(g) determining a second acute hemodynamic response in reaction to the electrical energy delivered to the test location;
(h) determining whether the second acute hemodynamic response is satisfactory;
(i) repeating steps (a) through (h) until the test location that yields a satisfactory second acute hemodynamic response is identified; and
(j) implanting the electrode at the identified site.

Abstract
Methods and apparatus for determining an endocardial implantation site for implanting an electrode, such as a leadless stimulation electrode. An embodiment of one method in accordance with the invention includes delivering sufficient electrical energy for initiation of cardiac activation to a plurality of different test locations at the heart of a patient, and determining hemodynamic responses in reaction to that the stimulus delivered to the different test locations. This method further includes identifying an implantation site for implanting the electrode by selecting at least one of the test locations corresponding to a favorable hemodynamic response.
