“I should avoid metal detectors and electric razors while wearing the monitor.”
“I should keep a log of any chest pain, shortness of breath, or skipped beats while wearing the monitor.”
Number 1 is correct.
Rationale: The Holter monitor cannot be worn while swimming or bathing and should be kept dry. The monitor stays in place for the entire time monitoring is performed, including sleep. Metal detectors, electric razors, microwaves, and other electrical devices may interfere with the signal and should be avoided. Cell phones should be kept at least 6 inches away from the monitor. Clients should keep a log and note any chest pain, shortness of breath, or skipped heart beats while wearing the monitor.
