What is a holter monitor?

ANSWER

A holter monitor is a portable EKG that monitors the electrical activity of your heart, generally for one to two days. It's most often used when your doctor thinks you might have an abnormal heart rhythm or there's not enough blood flow to your heart muscle (called ischemia).

It's a painless test; electrodes from the monitor are taped to your skin. Once the monitor is in place, you can go home and do all your normal activities (except showering). You'll be asked to keep a diary of your activities and any symptoms you have.
