Premature Atrial Contractions
Medically reviewed by Drugs.com. Last updated on Apr 6, 2025.
Premature atrial contractions (PACs) are an interruption in your heart rhythm. PACs happen when your heart gets an early signal to pump. PACs are common and usually have no cause. Most people have skipped heartbeats from time to time. Follow up with your healthcare provider so the cause of your PAC can be diagnosed and treated.
DISCHARGE INSTRUCTIONS:
Call 911 for any of the following:
You have any of the following signs of a heart attack:
- Squeezing, pressure, or pain in your chest
- You may also have any of the following:
- Discomfort or pain in your back, neck, jaw, stomach, or arm
- Shortness of breath
- Nausea or vomiting
- Lightheadedness or a sudden cold sweat
Contact your healthcare provider if:
- Your symptoms do not go away, or they get worse.
- You have questions or concerns about your condition or care.
Medicines:
- Medicines may be given to make your heart beat at a regular rate and rhythm.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Follow up with your healthcare provider as directed:
Bring your Holter monitor and results with you. Write down your questions so you remember to ask them during your visits.
Prevent more PACs:
- Do not have alcohol or caffeine. These can increase your PACs.
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars can increase heart problems. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Exercise as directed. Exercise helps keep your heart healthy. Ask your healthcare provider about the best exercise plan for you.
