UNDERSTANDING YOUR PROCEDURE
Your guide to
pulsed field ablation
For atrial fibrillation (AFib) · Before and after your procedure
Read this guide before your procedure. Keep it during recovery, especially the “When to get help” section. This guide describes pulsed field ablation (PFA), not every type of AFib ablation.
What is AFib, and why have an ablation?
AFib is an irregular, often fast heartbeat that starts in the upper chambers of the heart. It can cause palpitations, shortness of breath, tiredness, and difficulty doing your usual activities.
Many AFib triggers come from where the pulmonary veins—the veins bringing blood from the lungs—join the heart. Ablation creates small areas of treated tissue to block these signals. This is called pulmonary vein isolation. The goal is to reduce AFib episodes and improve symptoms and quality of life. Your team will explain why ablation is an option for you.
How is PFA different?
Other ablation methods use heat or cold. PFA uses brief electrical pulses that disrupt targeted heart-muscle cells, rather than heating or freezing them. It can limit injury to some nearby tissues, but it is not risk-free.
In a randomized study of people with intermittent (paroxysmal) AFib, PFA performed similarly to heat- or cold-based ablation at one year. Results vary with the type of AFib, the device, and your health. AFib can return, and some people need another procedure.
Benefits and risks
Possible benefits include fewer AFib episodes, better symptoms and quality of life, and sometimes less need for rhythm-control medication. These benefits are not guaranteed.
Risks include bleeding or blood-vessel injury in the groin; fluid around the heart that may need drainage; stroke or TIA; anesthesia-related complications; and, rarely, death. PFA-specific concerns include coronary artery spasm and red-blood-cell breakdown that can affect the kidneys. Studies have reported low rates of injury to the esophagus, pulmonary veins, and phrenic nerve, but that does not mean these risks are impossible. Your team will discuss your personal risks and alternatives before consent.
Getting ready
Your blood thinner plan
Blood thinners help lower the risk of stroke around ablation. Do not stop, skip, or change a dose on your own. Use the medication-specific plan below. Before ablation, report any unplanned missed blood thinner doses to the EP team because this may change the need for clot-check imaging or the procedure date. A dose intentionally held under your written plan is not a missed dose.
Anticoagulation plan
Food and drink plan
SGLT2 medicines
GLP-1 receptor agonists
Add other preparation instructions if needed.
Other medicines, tests, and arrangements
- Use your written medication plan for rhythm/rate medicines, diabetes medicines, aspirin, and other blood thinners. Bring an up-to-date medication list.
- You may need blood tests, an ECG, or imaging. A TEE (an ultrasound through the swallowing tube) or CT may be used to check for a clot. Complete the tests listed in your appointment instructions.
- Use the food and drink plan above. A different personalized anesthesia instruction takes priority.
- Do not drive yourself home after general anesthesia. Arrange an adult driver and someone to stay with you the first night.
On the day
The procedure takes place in an electrophysiology (EP) lab. You receive general anesthesia, so you are asleep during the procedure. Thin tubes called catheters enter through a vein in the groin and are guided to the heart. The doctor crosses between the upper chambers to reach the left atrium, then uses PFA to isolate the pulmonary veins. Additional areas may be ablated if needed, based on the findings during the procedure and your agreed treatment plan. IV blood thinner is given during the procedure.
Plan for several hours at the facility; your team will give you an estimate. The total visit includes preparation and recovery, not just the ablation.
Your recovery
Before you go home
You will rest while staff check your groin sites, heart rhythm, and vital signs. Follow their instructions about lying flat and getting up. Many patients go home the same day; others stay overnight.
Take your blood thinner according to the restart plan provided at discharge. After AFib ablation, the usual U.S. recommendation is to continue anticoagulation for at least 3 months, and longer when your stroke risk warrants it. Do not stop at 3 months on your own or because your rhythm feels normal.
If you miss a blood thinner dose after discharge
These instructions apply after your prescribed restart time, not to doses deliberately held for the procedure. Your clinician can mark the applicable row below. Use only the line for your medicine. Do not take extra doses to catch up.
- □ Apixaban (Eliquis): Take the missed dose as soon as you remember on the same day, then resume your twice-daily schedule. Do not double a dose.
- □ Rivaroxaban (Xarelto), once-daily AF dose: Take it as soon as you remember that day, with food for the 15 mg or 20 mg dose. Resume your usual schedule the next day. Do not take two doses in one day. This is not the twice-daily blood-clot treatment regimen.
- □ Dabigatran (Pradaxa): Take it only if at least 6 hours remain before your next scheduled dose. Otherwise skip it and take the next dose on schedule. Do not double.
- □ Edoxaban (Savaysa): Take it as soon as you remember on the same day; return to your normal schedule the next day. Do not double.
- □ Warfarin: Take the missed dose if you remember the same day. Do not double the next day. Notify your anticoagulation clinic and follow its INR plan.
For repeated missed doses, vomiting that prevents taking medicine, bleeding, or conflicting instructions, contact your team. Use emergency care for severe bleeding or stroke symptoms.
What you may notice
Tiredness, groin bruising or tenderness, and a sore throat after a breathing tube or TEE may occur. Mild chest discomfort can also occur, but do not assume new, worsening, or persistent symptoms are normal—use the warning-sign guidance.
Palpitations or AFib can happen during the early healing period and do not necessarily mean the procedure failed. Report persistent or concerning symptoms to your team. They may continue rhythm medicine and arrange monitoring.
Activity and follow-up
Use the routine recovery instructions below unless your discharge paperwork gives different limits. Do not drive while impaired by sedation or pain medicine; use the driving and return-to-work dates in your discharge paperwork.
Routine recovery instructions appear when the workspace loads.
Routine follow-up instructions appear when the workspace loads.
Follow the medication and appointment details in your personalized discharge instructions.
When to get help
Call 911 for emergency symptoms
- Sudden weakness or numbness, facial drooping, trouble speaking or understanding, sudden vision changes, or a severe sudden headache.
- Severe or worsening chest pain, severe trouble breathing, fainting, or a very fast heartbeat with severe symptoms.
- Heavy groin bleeding that does not stop with firm pressure, rapidly growing swelling, or a cold, pale, or numb leg.
Do not drive yourself if you may be having an emergency.
Seek urgent medical assessment
Get urgent help for new trouble or pain with swallowing, coughing up blood, worsening breathlessness, persistent near-fainting, or fever/chills with chest or swallowing symptoms. These matter even weeks after ablation. If symptoms are severe, call 911. Tell the treating team that you recently had heart ablation and when it occurred.
Contact your care team promptly
- AFib, palpitations, or a fast/irregular pulse that does not settle or concerns you.
- Fever, increasing groin swelling or pain, or chest discomfort that persists or changes.
- Repeated missed blood thinner doses, inability to keep the medicine down or obtain it, or a missing or conflicting restart plan. For one missed dose after discharge, use the drug-specific instructions in this guide. Warfarin users should also notify their anticoagulation clinic.
If you cannot reach your team, use its after-hours route or seek urgent care. If you are unsure whether symptoms are an emergency, seek emergency help.
This is general education, not a replacement for your care team’s instructions or consent discussion. Follow your personalized plan, especially for blood thinners and fasting.
