Which system directly receives, records and displays all ECG/EGM signals from ECG electrodes and EP catheters?

• A. Recording system
• B. Display monitor
• C. Signal processor
• D. Printer

Answer: (A)

In electrophysiology, capturing and reviewing all ECG and intracardiac signals is handled by the recording system. It sits at the input end, directly receiving the analog signals from all ECG leads and EP catheters, then digitizing them with high sampling rates, buffering and time-stamping the data, and storing it for later review. It also provides a live display of the waveforms, feeding that view to the display interface so you can monitor in real time. The display monitor itself is mainly for viewing what the recording system shows, not for capturing or archiving the data by itself. The signal processor performs filtering and analysis on signals that have already been captured, rather than being the primary source of data capture. The printer outputs copies of recorded data rather than handling real-time recording and display.
