Fig 4. RA and the CT rotor meandering area in relationship with the near and far basket electrodes in the SVC, CT and CS positions.

Fig 4

A) Meandering area of the CT rotor (black) and region of the endocardium located at a distance d ≤ 0.5 cm (red) and 0.5 < d ≤ 1.0 cm (green) from at least one electrode for the SVC (top), CT (middle) and CS (bottom) positions. Panels illustrating the positions of the basket inside the RA have been also included on the left side for clarity. Right side column depicts EGM traces from electrodes set at d ≤ 0.5 cm (red) and 0.5 < d ≤ 1.0 cm (green) for the SVC, CT and CS positions. B) RA coverage by the basket computed as the ratio between the section of the endocardium at a distance d ≤ 0.5 cm (red) and 0.5 < d ≤ 1.0 cm (green) from at least one electrode over the whole interface for the three basket positions. C) Coverage of the CT rotor meandering area computed as the ratio between the section of the meandering area overlapped to the RA coverage over the whole meandering area. SVC and IVC: superior and inferior vena cava; LA and RA: left and right atrium; RPV: right pulmonary veins; TVR: tricuspid valve ring; CS: coronary sinus; RAA: right atrial appendage.
