A Closer Look at Sleep Apnea and AFib

What is Sleep Apnea?

Sleep apnea is a serious sleep problem that interrupts a person’s breathing during their sleep. People with sleep apnea stop breathing or have shallow breathing during their sleep. This means the body and the brain do not get enough oxygen.

A person with sleep apnea will wake up when their brain doesn’t get enough oxygen. This can happen hundreds of times each night. Some people may not even be aware that they are waking from sleep so often. People living with sleep apnea may snore loudly and often wake from sleep gasping for air or have the feeling of choking. They may also feel a lot of daytime sleepiness or tiredness. Some people have trouble falling asleep and can become depressed.

Some people are more likely to get sleep apnea than others. You have a higher chance of getting sleep apnea if:

  • You are male
  • You are overweight
  • You have a wide neck (greater than16 inches around in women and 17 inches in men)
  • You have high blood pressure
  • You smoke
  • You have diabetes
  • You have a family history of sleep apnea

Sleep apnea is diagnosed by an overnight sleep test, which can be done at home or in a special sleep laboratory. The sleep test measures the number of times during your sleep you either stop breathing or your breathing becomes very shallow. It also measures the level of oxygen in your blood and keeps track of the brain and heart activity during sleep.

Each time a person with sleep apnea is startled awake by lack of oxygen during their sleep, the heart is stressed. This may lead to AFib. About half of patients with AFib also have sleep apnea. Preventing sleep apnea makes AFib treatments (medicine and surgeries) more effective.

Untreated sleep apnea can lead to problems like high blood pressure and diabetes, which in turn can lead to AFib. Long-term untreated sleep apnea can also cause problems with thinking and higher chance of accidents and stroke.

Talk to your doctor about sleep apnea to find out if you may need to be tested. Start by telling your doctor about any snoring or daytime sleepiness that you may have. Treating sleep apnea can improve your quality of life and lower your chance of a heart attack or stroke.

Heart Rhythm Disorders
Millions of people experience irregular or abnormal heartbeats, called arrhythmias, at some point in their lives. Most of the time, they are harmless and happen in healthy people free of heart disease. However, some abnormal heart rhythms can be serious or even deadly. Having other types of heart disease can also increase the risk of arrhythmias.
Pediatrics and Congenital Heart Disease (CHD)
This section is for pediatric patients and families living with heart rhythm disorders and heart rhythm disorders related to congenital heart disease (CHD).
Early Warning Signs
If you are experiencing a racing, pounding, rumbling or flopping feeling in your chest or if you have been fainting, having repeated dizzy spells, feeling lightheaded or you are extremely fatigued, it's time to see a doctor to discuss your heart health.
Common Treatments
Learning about the underlying cause of any heart rhythm disorder provides the basis for selecting the best treatment plan. Information and knowledge about care options, and their risks and benefits help you work with your health care provider to make the best choices.
Lifestyle
Since other heart disorders increase the risk of developing abnormal heart rhythms, lifestyle changes often are recommended. Living a “heart healthy” lifestyle can ease the symptoms experienced with heart rhythm disorders and other heart disorders, and can be beneficial to overall patient health.
The Normal Heart
The heart is a fist-sized muscle that pumps blood through the body 24 hours a day, 365 days a year, without rest. The normal heart is made up of four parts: two atria on the top of the heart (right atrium and left atrium), and two ventricles (right ventricle and left ventricle) which are the muscular chambers on the bottom of the heart that provide the major power to pump blood.
