According to some embodiments of the present disclosure, a method for detecting deliberate motion of a catheter positioned within a patient and including a magnetic sensor includes collecting a plurality of first magnetic sensor samples. The method includes measuring a sensor position Pin 3D coordinates for each of the first magnetic sensor samples and measuring a sensor orientation for each of the first magnetic sensor samples. Measuring the sensor orientation includes generating a first vector (P-P) and generating a second vector (P-P) orthogonal to the first vector. The method includes removing a respiration motion frequency component from the from the plurality of first magnetic sensor samples with a signal processing filter. A running variance for each axis (x, y, z) of the Pand Pis computed. The method includes generating an output indicative of detected deliberate motion based on the computed running variance.
