摘要： Disclosed is a sensor for a catheter comprising: a first coil at a location within the catheter and electrically insulated by the catheter, for outputting signals for determining the position of the first coil within the body; and, a second coil along the outside of the catheter, the second coil including an uninsulated portion of a predetermined number of windings configured to output 1) electrocardiogram (ECG) signals, and, 2) signals indicative of voltages corresponding to tissue impedance from a magnetic field through body tissues and/or fluids.

摘要： Values of an R-to-end-of-T interval and an RR interval for multiple ECG cycles of a patient are obtained. Based on the values, a relationship between the RR interval and the R-to-end-of-T interval or another variable derived therefrom is computed, the relationship being for use in computing a delay from an R-peak of any subsequent ECG cycle of the patient to a time window in which to apply PEA to the patient's heart such that the time window is expected to start after an end of a T-wave of the subsequent ECG cycle and to end prior to a QRS-wave immediately following the subsequent ECG cycle. Subsequently, during a PFA procedure, a current cycle length or heart rate of the patient is obtained, the delay is computed, using the relationship, based on the current cycle length or heart rate, and PFA is applied during the time window following the delay.

摘要： In one embodiment, a method includes receiving first intracardiac signals including first far-field components captured by at least one first sensing electrode of a first catheter, the at least one sensing electrode being in contact with tissue of a cardiac chamber of a first living subject, and at least one far-field signal captured from at least one far-field electrode inserted into the cardiac chamber and not in contact with the tissue of the cardiac chamber, training a neural network to remove far-field components from intracardiac signals responsively to the first intracardiac signals and the at least one far-field signal, receiving second intracardiac signals captured by at least one second sensing electrode of a second catheter inserted into a cardiac chamber of a second living subject, and applying the trained neural network to the second intracardiac signals to remove respective second far-field components from the second intracardiac signals.

摘要： A medical apparatus includes a shaft for insertion into an organ of a patient, an expandable frame, a plurality of diagnostic electrodes, a respective plurality of reference electrodes, and a processor. The expandable frame is coupled to a distal end of the shaft, extending along a longitudinal axis and including a plurality of expandable spines disposed about the longitudinal axis. The plurality of diagnostic electrodes, disposed on external surfaces of the expandable spines, are configured to sense diagnostic signals when in contact with tissue. The respective plurality of reference electrodes, disposed on internal surfaces of the expandable spines directly opposite the diagnostic electrodes, is electrically insulated from the tissue and is configured to sense interfering signals. The processor is configured to receive the diagnostic signals sensed by the diagnostic electrodes, receive the interfering signals sensed by the respective reference electrodes, and calculate corrected diagnostic signals by subtracting the interfering signals from the diagnostic signals.
