Abstract:
1. A method for identifying an optimal pacing location, comprising: a. introducing an acceleration-measuring catheter into a coronary sinus of a patient; b. measuring a baseline pattern of left ventricular myocardial acceleration; c. placing a right ventricular pacing device in a right ventricle of the patient; d. placing a left ventricular pacing device in or on the left ventricle of the patient; e. moving the left ventricular pacing device to a plurality of locations in or on the left ventricle; f. performing biventricular or left ventricular pacing at each of the plurality of locations with the left ventricular pacing device; g. measuring an acceleration pattern at each of the plurality of locations caused by the biventricular or left ventricular pacing; and h. determining a location within the left ventricle having a least dyssynchronous acceleration pattern; and i. selecting the location with the least dyssynchronous acceleration pattern to implant a CRT pacing lead.
