The ECH log was a log kept by The Doctor on the USS Voyager while he was an Emergency Command Hologram and was in command of Voyager. The log was a counterpart to a Captain's log and took the place of the Voyager's captain's log while he was in command. (VOY: "Workforce, Part II")
There were at least two log entries made into the ECH log:
- "ECH log, Stardate 54622.4. I've found an ingenious place to hide while we make repairs – a moon with a paramagnetic core that masks our energy signature. I've turned my attention to Lieutenant Torres, whose treatment will also require ingenuity."
- "ECH log, supplemental. All the crew have been transported back to Voyager, and thanks to my experience with Lieutenant Torres, their treatment is proceeding rapidly. While they're recovering, I still have a few command duties left to perform."
