ECG monitoring is similar to a normal electrocardiogram (ECG) except the electrodes are connected to a small recording device, sometimes called a holter monitor, which you will wear on a belt. It measures the heart's electrical activity and rhythm to track changes over a period of time.
What's involved in ECG monitoring?
Several electrodes will be gently stuck onto the skin on your chest. Wires from these will be connected to the holter monitor or recording device which you will wear around your waist. The recorder will either record continuously over a period (such as 24 or 48 hours), or you will be asked to turn it on when certain symptoms are felt.
You will be required to return to the hospital after the period of recording is complete. Your doctor will review the readings of the ECG recorder, which appear as a series of waves.
