How will the Test Feel?
During the test, you are awake and able to follow instructions. A small incision is made into a vein in your arm, neck, or groin in order to thread the catheter into the heart. Local anesthesia is applied to the area before the catheter is inserted. The sensation you feel is pressure (not pain) at that site.
Remaining still for a prolonged period of time may make you feel somewhat stiff and uncomfortable.
When the electrical tissue of the heart is tested, you may feel your heart beating faster or stronger. If an arrhythmia is induced as part of the test, the doctor may use medication or electrical energy to terminate it.
The procedure generally lasts from one to several hours.
