Final answer:
The Holter monitor typically records the heart's electrical activity for a 24-hour period to provide detailed insights into both normal and abnormal heart functions.
Step-by-step explanation:
A Holter monitor is a small, portable, battery-operated device that continuously monitors the heart's electrical activity, commonly for a period of 24 hours during the patient's normal daily activities.
By recording an electrocardiogram (ECG or EKG), this device helps in providing a detailed picture of both normal and abnormal heart function and is an indispensable tool in clinical diagnostics.
It involves careful placement of surface electrodes on the body to trace the electrical signals of the heart using an electrocardiograph with varying numbers of leads, where a 12-lead using 10 electrodes gives more information.
A Holter monitor is typically worn for a period of 24 hours. It is a small, portable, battery-operated device that continuously monitors the electrical activity of the heart.
This device is used to detect and record abnormal heart rhythms or arrhythmias that may not be captured during a short-term ECG test.
