Abstract:
1. Apparatus, comprising: a cardiac catheter; an EP recording system; a channel connecting the cardiac catheter and the EP recording system, the channel having a first path and an alternate path that bypasses the first path, the channel being configured to deliver Electro-Physiological (EP) signals from the cardiac catheter to the EP recording system and pacing signals from the EP recording system to the catheter; a sensing unit connected to the cardiac catheter and the EP recording system over the channel, the sensing unit being configured to automatically identify time intervals during which the pacing signals are delivered; and control circuitry connected to the sensing unit and configured to route the EP signals on the channel from the catheter to the EP recording system via the first path, to switch the channel to the alternate path during the identified time intervals, and to route the pacing signals from the EP recording system to the cardiac catheter over the alternate path.
