Abstract
A method is provided. The method includes pacing, by electrodes of a catheter, a heart tissue with pulses. The method includes observing, by the electrodes, a period of electrophysiological repolarization for the heart tissue. The period of electrophysiological repolarization is caused by the pacing. The method also includes measuring, by the electrodes, an electrical signal within the heart tissue after the period of electrophysiological repolarization.
Claims20
A method comprising:
- detecting, by a plurality of electrodes of a catheter, a period of electrophysiological repolarization for a heart tissue caused by a pacing of the heart tissue by the catheter with a plurality of pulses;
- measuring, by the plurality of electrodes of the catheter, an activity pattern of returning electrical signals propagating from the heart tissue after the period of electrophysiological repolarization, wherein the pacing of the heart tissue by the catheter generates a region of the heart tissue where waves, other than the plurality of pulses, are prohibited from entering until after the period of electrophysiological repolarization to enable the measuring of the activity pattern.
An apparatus comprising:
- a catheter comprising a plurality of electrodes;
- and
- a cardiac pacing and diagnosis device comprising a memory storing processor executable instructions of cardiac pacing and diagnosis software, and a processor configured to execute the processor executable instructions of the cardiac pacing and diagnosis software to cause the apparatus to:
- detect, by a plurality of electrodes of a catheter, a period of electrophysiological repolarization for a heart tissue caused by a pacing of the heart tissue by the catheter with a plurality of pulses;
- measure, by the plurality of electrodes of the catheter, an activity pattern of returning electrical signals propagating from the heart tissue after the period of electrophysiological repolarization, wherein the pacing of the heart tissue by the catheter generates a region of the heart tissue where waves, other than the plurality of pulses, are prohibited from entering until after the period of electrophysiological repolarization to enable the measuring of the activity pattern.
