`Holter heart monitor
`
`Overview
`
`During a heart Holter monitor study, the patient wears a monitor that records electrical activity of their
`heart (similarly to the recording of an electrocardiogram). This usually occurs for 24 hours, while at the
`same time the patient also records a diary of their activity. Health care providers then analyze the
`recording, tabulate a report of the heart's activity, and correlate irregular heart activity with the entries of
`the patient's diary.
