摘要： A method of mapping includes receiving inputs measured by a probe at respective locations inside a body cavity of a subject. At each of the respective locations, a respective contact quality between the probe and a tissue in the body cavity is measured. The inputs for which the respective contact quality is outside a defined range are rejected, and a map of the body cavity is created using the inputs that are not rejected.

摘要： A method for position tracking includes placing an internal reference probe in a reference location within a heart of a subject, and collecting and processing first location coordinates of the internal reference probe during one or more respiratory cycles so as to define a range of the location coordinates corresponding to the reference location. An active device is inserted into the heart, and second location coordinates of the active device are collected. The first and second location coordinates are jointly processed so as to find relative location coordinates of the active device in a cardiac frame of reference. When a deviation of the first location coordinates from the range is detected, the relative location coordinates are corrected to compensate for displacement of the reference probe from the reference location.

摘要： Ventricular tachycardia signals are induced in a living subject. Pace-mapped signals are then obtained from multiple points within the ventricle, and automatically compared numerically with the induced signals. Recognition of a high degree of cross correlation between the induced signals and one or more of the pace-mapped signals identifies arrhythmogenic foci or pathways, which may then be ablated, so that the arrhythmia becomes non-inducible.

摘要： A method for tracking a position of a sensor includes generating a periodic magnetic field in a vicinity of the sensor, the field having a positive polarity phase and a negative polarity phase with respective constant positive and negative amplitudes. First and second field measurement signals are produced responsively to the magnetic field at the sensor during the positive and negative polarity phases, respectively. The position of the sensor is determined responsively to the first and second field measurement signals.
