Abstract
A method is provided. The method is implemented by an interpretation engine executed by processors coupled to a memory. The method includes receiving a bipolar intracardiac reference signal from reference electrodes of a catheter and executing a preprocessing of the bipolar intracardiac reference signal. The method further includes interpreting the bipolar intracardiac reference signal according to a threshold for contact by a reference electrode of the electrodes.
Claims21
A method comprising:
- receiving, by an interpretation engine executed by one or more processors coupled to a memory, a bipolar intracardiac reference signal from a plurality of reference electrodes of a catheter;
- executing, by the interpretation engine, a preprocessing of the bipolar intracardiac reference signal;
- and
- interpreting, by the interpretation engine, the bipolar intracardiac reference signal according to a threshold for contact by a reference electrode of the plurality of electrodes.
A system comprising:
- a memory storing program code for an interpretation engine thereon;
- and
- one or more processors configured to execute the program code to cause the system and the interpretation engine to:
- receive a bipolar intracardiac reference signal from a plurality of reference electrodes of a catheter;
- execute a preprocessing of the bipolar intracardiac reference signal;
- and
- interpret the bipolar intracardiac reference signal according to a threshold for a contact by a reference electrode of the plurality of electrodes.
The system of claim 11, wherein the preprocessing comprises a power noise removal filter, high pass filter, or median filtering.
