Final answer:
Event monitors record the heart's electrical activity on an episodic basis when activated by a patient or during detected arrhythmias, which is true.
Step-by-step explanation:
The statement that event monitors do not record continuously and that data is reported on an episodic basis is true. Event monitors are medical devices used to record the heart's electrical activity, but unlike continuous cardiac monitors, they do not record data all the time. These monitors are designed to record data when a patient activates them during certain symptoms or irregularities, or they may automatically record during detected arrhythmias. This method allows for monitoring over extended periods without the need for continuous data storage or analysis.
