How well a pacemaker is functioning
Details about previous surgeries

The correct answer is: How well a pacemaker is functioning

A Holter monitor is a portable device used to continuously monitor the electrical activity of the heart, typically over a 24 to 48-hour period. This device records various aspects of the heart's rhythm, which can provide crucial insights into the patient's cardiac function during daily activities. The correct option highlights that the Holter monitor can reveal how well a pacemaker is functioning. Pacemakers are devices implanted to help control abnormal heart rhythms. After pacemaker installation, monitoring its performance is vital to ensure the device is operating correctly, delivering appropriate electrical impulses, and maintaining the heart rate as intended. The data collected by the Holter monitor can show whether the pacemaker is pacing the heart as it should or if there are any irregularities that need addressing. The other options do not accurately represent the capabilities of a Holter monitor. While monitoring heart rhythms is central to its function, it does not measure steps taken, evaluate blood pressure levels, or provide information about previous surgeries, which are not related to cardiac rhythm monitoring.
