Premature Atrial Contractions
WHAT YOU NEED TO KNOW:
What are premature atrial contractions (PACs)?
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.
What increases my risk for PACs?
- Stress or fatigue
- Caffeine, alcohol, or tobacco
- Medical conditions, such as high blood pressure, heart disease, or hyperthyroidism
What are the signs and symptoms of PACs?
- Palpitations (fast, forceful heartbeats in an irregular rhythm)
- A missed or skipped heartbeat
- Chest pain or shortness of breath
- Lightheadedness, dizziness, or feeling faint
- Tiredness with exercise or activity
How are PACs diagnosed?
Your healthcare provider will ask if you have a family history of heart problems. You may also need any of the following:
- An EKG records your heart rhythm and how fast your heart beats. It is used to check for PACs.
- A Holter monitor is a device that you wear for a period of time. It records how fast your heart beats, and if it beats in a regular pattern. You may need to wear it up to 72 hours. This will show how frequent your PACs are during your normal daily activities.
How are PACs treated?
PACs usually do not need treatment. You may be given medicine to strengthen or regulate your heartbeat.
How can I help 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.
