System and method for determining optimal pacing sites based on myocardial activation times |
摘要 |
The optimal location for delivering pacing pulses to a given cardiac chamber (such as the left ventricle) is determined by identifying the last electrically or mechanically activated site within the chamber. For example, the last site within the left ventricular myocardium to depolarize during an intrinsic ventricular contraction triggered by an initial atrial depolarization is identified as being the optimal pacing location for the left ventricle. A pacing electrode is then implanted as close as possible to that location. The technique is particularly effective for use in identifying optimal epicardial pacing locations for mounting satellite pacing devices for use in delivering cardiac resynchronization therapy. However, the techniques may also be applied to identify locations for mounting endocardial electrodes as well. Capture thresholds may also be taken into account in determining the optimal location. Examples are described for both master/satellite pacing systems as well as biventricular single device systems. <IMAGE>
