Your doctor may recommend an EPS test to pinpoint where in your heart your arrhythmia occurs and to check the severity of your condition.
In an EPS test, a catheter is threaded through a vein in your groin to your heart, similar to cardiac catheterization. Electrodes are then passed through the catheter to different points in your heart. The electrodes then map out any irregular heartbeats. The electrodes don’t shock your heart — they just detect the electrical signals running through your heart. This will help your physician determine what the appropriate treatment will be for your condition.
