Abstract: A method and apparatus for electrophysiological assessment, including acquiring electrical signals from tissue at locations in a heart chamber and a computer processor automatically deriving from the electrical signals annotations indicative of times within a heart cycle at which a conduction wave traversed the locations. The method includes receiving an input from a processor user indicating, for a first location in the tissue where the electrical signals include a double-potential signal, a first annotation as a valid annotation. The processor automatically identifies second locations, within a predefined distance from the first location, where the electrical signals include double-potential signals, each having two respective annotations. The method further includes the processor automatically selecting, in response to the selection of the first annotation, one of the two respective annotations as the valid annotation at each of the second locations and displaying the valid annotations on an electroanatomical map of the heart.

Abstract: A system including a medical probe having a tube with a distal end for insertion into a cardiac chamber, an electrode at the distal end that conveys energy to myocardial tissue, a temperature sensor at the distal end that outputs a signal indicating a temperature of the tissue, a channel contained within the tube that delivers fluid to the distal end, and a fluid port at the distal end and coupled to the channel. The system also includes a generator that applies a specified level of the energy to the electrode, a pump that forces the fluid into the channel at a controllable rate, and a processor that controls the rate responsively to the signal so that a difference between a specified temperature, which is no greater than 55° C., and the indicated temperature is no greater than ±2.5° C. while the generator applies a constant level of the energy.

Abstract: A system includes an expandable distal end of a catheter and a processor. The expandable distal end has multiple electrodes that are configured to be placed in contact with a tissue in an organ and to apply ablative power to tissue. The processor is configured to, during application of the ablative power, determine whether a physical contact between the electrodes and tissue meets a predefined contact quality, and, if the physical contact of an electrode among the electrodes with the tissue does not meet the predefined contact quality, re-use the electrode for electrophysiological (EP) sensing.
