Estimating the center of a rotor for AFib Ablation

In this paper, two algorithms are presented that analyze and identify the source of a rotating bar, called a rotor, moving at an unknown speed. Using sensors at known locations on the surface of the rotor, the sensors record the times when the rotor wave/bar passes them. With these data, the first algorithm uses concepts from rotational dynamics and node localization, while the second algorithm relies on the geometry of the sensor placement, to...
