Holter and Mobile Cardiac Monitors
Purpose
Your doctor uses Holter monitoring to determine how the heart responds to normal activity. The monitoring, usually over 1-2 days, helps the doctor diagnose heart rhythm problems that may be causing symptoms such as palpitations or syncope (passing out/fainting). Your doctor will order the event monitoring if no diagnosis is reached. The event monitor is also used for people who have symptoms that occur less often, such as weekly to monthly.
