You have just had a catheter-based EP procedure. The following instructions will help you recover safely and avoid complications. Please read through all of them carefully.
The first 10 days
The most important thing to keep in mind for the first 10 days is to protect the groin access site — this is where the catheters were inserted through a vein in your leg. This site takes time to fully seal and heal.
- Take it easy — avoid strenuous physical activity for 10 days
- Nothing heavier than 10 pounds for 10 days — lifting, straining, or anything that creates pressure in the groin area (including heavy grocery bags, carrying children, or straining on the toilet) can cause the vein access site to bleed
- Light walking around the house is fine and encouraged — just avoid anything that strains or compresses the groin
If the groin site bleeds
Occasionally the groin access site may begin to bleed after you are home. If this happens, do not panic — here is what to do:
1. Lie flat immediately — do not stay sitting or standing.
2. Apply gentle, firm pressure over the site with your hand or a clean cloth for 15 minutes — set a timer and do not peek before the time is up.
3. The pressure does not need to be forceful. The catheter was placed through a vein, not an artery — venous bleeding responds well to gentle sustained pressure.
4. If bleeding does not stop after 15 minutes of sustained pressure, call 911 or have someone drive you to the nearest emergency room.
Blood thinners — restart the same day
You will be restarted on your anticoagulation (blood thinner) the same day as your procedure — this is intentional. The risk of stroke is elevated for approximately 4 weeks following ablation, and it is critical that your blood thinner not be interrupted during this period.
Important: Because you cannot stop anticoagulation for 4 weeks after your procedure, this means no elective surgery can be performed during this window that would require stopping your blood thinner. If any surgeon or dentist recommends stopping your anticoagulation within 4 weeks of your procedure, please contact our office first before making any changes.
Bruising at the groin site
It is completely normal for the groin area to become bruised after the procedure. In some patients, this bruising can be quite dramatic — it may spread down the inner thigh and even travel toward the knee. This can look alarming but is expected.
What you are seeing is blood from the procedure tracking slowly through the tissue under the skin. It is not dangerous. The bruising will fully resolve over 4 to 6 weeks as the body gradually breaks down the old blood. No special treatment is needed.
Showering and bathing
You may shower or bathe starting the day after your procedure. Gently pat the groin site dry — do not scrub it. Avoid prolonged soaking in a bathtub or hot tub for the first week.
Chest discomfort — what is normal
It is normal to experience some chest discomfort in the days following ablation. The characteristic pattern of post-ablation chest pain is a sharp pain that is worse when you breathe deeply or bend forward — this is called pleuritic chest pain and reflects some irritation around the heart from the procedure.
This type of pain generally responds well to ibuprofen (Advil, Motrin) taken at the regular over-the-counter dose with food. If you cannot take ibuprofen, contact us for alternatives.
Nodule at the access site
During the healing process, some patients develop a small firm nodule or lump at the groin access site. This is a normal part of healing — scar tissue forming around the vein entry point. It is not dangerous and does not require treatment. It will gradually soften and resolve on its own over weeks to months.
When to call us
- Groin bleeding that does not stop with 15 minutes of pressure
- Increasing pain, redness, warmth, or discharge at the groin site (signs of infection)
- Fever above 101°F (38.3°C)
- New or worsening leg swelling or pain
- Any chest pain or symptoms that concern you
- Palpitations, dizziness, or fainting
- Any question at all — we would rather you call than wonder
Recovery from EP procedures is generally smooth and straightforward. Most patients feel well within a few days. The key is protecting that groin site, restarting your blood thinner on time, and not hesitating to call if something does not feel right.
