Abstract: A system and method for voltage-guided anatomical shell editing includes outputting, to a display device, an anatomical shell of a cardiac structure. The anatomical shell is based on signals sensed by a mapping probe, each signal including a respective sensed voltage. User input specifying a first target depth for editing is received, as is a selection of a first region of the anatomical shell. A modified anatomical shell is generated by removing a first portion of the anatomical shell including the selected first region to a first editing depth based on the first target depth and generating a new surface region on the modified anatomical shell. Based on the voltage associated with the new surface region, the edit can be maintained, undone, and/or modified.

Abstract: Medical devices and method for generating multi-time scale waveforms for display of sensor measurements are disclosed. Sensed or measured output signals from a sensor, such as a catheter, are processed to generate a first data set that uses a first time scale and a second data set that uses a second time scale. The generated data sets are then displayed on a display by juxtaposing the first data set with the second data set. In this manner, measurement data from the sensor can be shown in dual time scales that allow for faster and more efficient visual diagnostic assessments.
