The individual also keeps a diary of activities and symptoms during the monitoring period. When the 24-hour heart recording and diary are complete, the doctor will compare the events of the day to the heart's activities. The doctor will try to match abnormalities on the heart recording with entries in the diary. Computers are also used to look for heartbeat irregularities in the recording. A person having this test should receive instructions from a healthcare provider on how to properly prepare for the test.
Abnormal results show irregular heart rhythms.
By comparing the diary entries with the heart record, the doctor may be able to determine the cause of the arrhythmias. For example, if the rhythm disturbances are connected with stressful events, there may be an emotional basis for the arrhythmias that can be treated with stress management. Examining the diary along with the Holter monitor results can also suggest various physical reasons for the arrhythmias.
