Cardiac Catheterization - How It Feels
About this test
You will feel a sharp sting when the local anesthetic is injected to numb your skin over the catheter insertion site. When the catheter is inserted, you may feel a brief, sharp pain. The movement of the catheter through your blood vessel may cause a feeling of pressure, but it is not usually considered painful. People commonly experience skipped heartbeats for a few seconds when the catheter touches the walls of the heart.
If a dye (contrast material) is injected, you may feel warm and flushed and have a metallic taste in your mouth. Some people feel sick to their stomach or have a headache. You also may feel nauseous or lightheaded, have chest pain, irregular heartbeats, an urge to cough, mild itching, or hives from the contrast material. If you have any of these symptoms, tell your doctor how you are feeling.
The temperature in the catheterization lab is kept cool so that the equipment does not overheat. For many people, the most difficult aspect of the test is having to lie still for an hour or more on the hard table. You may feel some stiffness or cramping.
Call your doctor immediately if you have chest pain, extreme shortness of breath, dizziness, trouble speaking or swallowing, or paralysis in any part of your body during or after the test.
You may experience some soreness and bruising at the insertion site. This is temporary and should disappear within 2 weeks. It is normal for the site to feel tender for about a week. Call your doctor immediately if:
- Your arm or leg becomes pale, cold, painful, or numb.
- Redness, swelling, or discharge from the catheter insertion site develops.
- You have a fever.
