Electrogram annotation system

A method comprising:

• providing, for display by a head-mounted display (HMD) worn by a user, a holographic rendering of intracardiac geometry including position of a catheter;
• providing, for display by the HMD, an electrogram waveform generated using data collected from the catheter, wherein the electrogram waveform is displayed adjacent to the holographic rendering;
• determining a gaze direction of the user by processing sensor data from the HMD;
• providing, for display by the HMD, a marker overlaid on the electrogram waveform at a location based on an intersection point between the gaze direction and the electrogram waveform;
• determining a first position of a first measurement graphic by tracking the location of the marker;
• determining a second position of a second measurement graphic by tracking the location of the marker,
• determining a measurement of the electrogram waveform based on a distance between the first position and the second position;
• and
• providing, for display by the HMD, the measurement of the electrogram waveform adjacent to the electrogram waveform.

A non-transitory computer-readable storage medium storing instructions, the instructions when executed by one or more processors cause the one or more processors to:

• provide, for display by a head-mounted display (HMD) worn by a user, a holographic rendering of intracardiac geometry including position of a catheter;
• provide, for display by the HMD, an electrogram waveform generated using data collected from the catheter, wherein the electrogram waveform is displayed adjacent to the holographic rendering;
• determine a gaze direction of the user by processing sensor data from the HMD;
• provide, for display by the HMD, a marker overlaid on the electrogram waveform at a location based on an intersection point between the gaze direction and the electrogram waveform;
• determine a first position of a first measurement graphic by tracking the location of the marker;
• determine a second position of a second measurement graphic by tracking the location of the marker,
• determine a measurement of the electrogram waveform based on a distance between the first position and the second position;
• and
• provide, for display by the HMD, the measurement of the electrogram waveform adjacent to the electrogram waveform.
