A medical device, comprising: a catheter shaft with a plurality of electrodes coupled thereto; and a processor coupled to the catheter shaft, wherein the processor is configured to execute the following steps: collecting a set of signals from the plurality of electrodes, generating a data set from at least one of the set of signals, wherein the data set includes at least one known data point corresponding to signal data sensed and/or collected by the electrodes and one or more unknown data points corresponding to missing signal data from electrodes that were not able to sense and/or collect data, determining a distance between the at least one known data point and the at least one or more unknown data points, interpolating at least one of the unknown data points by conditioning the data set, wherein a weighted value of the at least one known data point is used, wherein the weighted value uses the determined distance, assigning an interpolated value to at least one of the unknown data points, and assigning a confidence level to the interpolated value, wherein the confidence level is determined based on the distance between the electrode with unknown data and the electrode(s) with known data that were used to interpolate the unknown data, and outputting to a display device (40, 182) the interpolated value and the assigned confidence level. a catheter shaft with a plurality of electrodes coupled thereto; and a processor coupled to the catheter shaft, wherein the processor is configured to execute the following steps: collecting a set of signals from the plurality of electrodes, generating a data set from at least one of the set of signals, wherein the data set includes at least one known data point corresponding to signal data sensed and/or collected by the electrodes and one or more unknown data points corresponding to missing signal data from electrodes that were not able to sense and/or collect data, determining a distance between the at least one known data point and the at least one or more unknown data points, interpolating at least one of the unknown data points by conditioning the data set, wherein a weighted value of the at least one known data point is used, wherein the weighted value uses the determined distance, assigning an interpolated value to at least one of the unknown data points, and assigning a confidence level to the interpolated value, wherein the confidence level is determined based on the distance between the electrode with unknown data and the electrode(s) with known data that were used to interpolate the unknown data, and outputting to a display device (40, 182) the interpolated value and the assigned confidence level. collecting a set of signals from the plurality of electrodes, generating a data set from at least one of the set of signals, wherein the data set includes at least one known data point corresponding to signal data sensed and/or collected by the electrodes and one or more unknown data points corresponding to missing signal data from electrodes that were not able to sense and/or collect data, determining a distance between the at least one known data point and the at least one or more unknown data points, interpolating at least one of the unknown data points by conditioning the data set, wherein a weighted value of the at least one known data point is used, wherein the weighted value uses the determined distance, assigning an interpolated value to at least one of the unknown data points, and assigning a confidence level to the interpolated value, wherein the confidence level is determined based on the distance between the electrode with unknown data and the electrode(s) with known data that were used to interpolate the unknown data, and outputting to a display device (40, 182) the interpolated value and the assigned confidence level.
