  • Publication number: 20170119453
    Abstract: A system and method for treating an arrhythmia in a heart are provided. The system includes an electronic control unit configured to monitor movement of one or more position sensor over a period of time. The position sensors may, for example, comprise electrodes or coils configured to generate induced voltages and currents in the presence of electromagnetic fields, The positions sensors are in contact with portions of heart tissue and changes in position are representative of motion of that tissue. The electronic control unit is further configured to generate an indicator, responsive to the movements of the sensors over the period of time, of a characteristic of the heart affected by delivery of ablation energy to heart tissue. In this manner, the effectiveness and safety of cardiac tissue ablation for treatment of the arrhythmia can be assessed and a post-ablation therapy regimen determined.
