The non-invasive ECG test helps your provider evaluate arrhythmias, chest pain, and structural heart problems as well as other heart conditions.
This test is performed by placing 12 electrodes (sticky pads) on the chest, arms and legs. Electrical signals from your heart are seen by the electrodes and sent to a machine that creates a graph of the heart rhythm and rate. This gives the ability to take a “snapshot” of the heart’s electrical activity. An ECG only captures electrical activity during the time the monitor is attached.
There are three forms of an ECG test:
- Resting ECG; a few second recording of the electrical activity in the heart from 12 different angles.
- ECG stress test; recording of the electrical activity of the heart at rest and with exercise on a treadmill.
- Ambulatory ECG; a small monitor using 3-5 patches that is worn for 24 hours to 30 days.
