Abstract
In one embodiment, a medical system includes a catheter to be inserted into a chamber of a heart of a living subject, and including catheter electrodes to contact tissue at respective locations within the chamber of the heart, a display, and processing circuitry to receive signals from the catheter, and in response to the signals, sample respective voltage values of the signals at respective timing values, and render to the display respective intracardiac electrograms (IEGM) presentation strips representing electrical activity in the tissue that is sensed by the catheter electrodes at the respective locations, each of the IEGM presentation strips including a linear array of respective shapes associated with, and arranged in a temporal order of, respective ones of the timing values, fillers of the respective shapes being formatted responsively to respective ones of the sampled voltage values of a respective one of the signals sampled at respective ones of the timing values.
