Atrial Fibrillation

Atrial fibrillation, or AFib, happens when the upper chambers of the heart, called the atria, beat in a fast and chaotic way. This disrupts the normal electrical signals that control heartbeats. The lower chambers, or ventricles, may also beat irregularly, leading to poor blood flow.

AFib affects people of all ages but is more common in older adults. Research suggests about 12 million Americans may have it by 2030 (Cleveland Clinic). It can be occasional or ongoing and may have no symptoms in some cases.

AFib is a progressive condition with stages from at-risk to permanent. Early detection might help manage it better. Talk to your doctor if you worry about heart rhythm issues.

Complications may include blood clots, stroke, or heart failure. Proper care can lower these risks. Many people live well with AFib under medical guidance.

AFib may stem from changes in the heart's electrical system or structure. Heart diseases like high blood pressure, coronary artery disease, or valve problems could trigger it. Other issues such as heart failure or prior heart surgery might play a role (Mayo Clinic).

Risk factors include older age, obesity, diabetes, sleep apnea, and thyroid problems. Excessive alcohol use or extreme endurance exercise over years may increase chances. Lack of activity or smoking could contribute too (Cleveland Clinic).

Genetics might factor in some cases, especially early-onset AFib. Serious illnesses like infections or COVID-19 could spark it temporarily. These factors often work together, so consult a healthcare professional for personal risks.

Doctors often start with an electrocardiogram (ECG or EKG), a quick test that graphs heart electrical activity. It can spot AFib's irregular pattern. A physical exam and medical history review help too (American Heart Association).

Other tests might include an echocardiogram (echo), an ultrasound to check heart structure and function. Blood tests rule out related issues like thyroid problems. Wearable monitors like Holter or event monitors track rhythm over days or weeks.

Your doctor may use scoring tools to gauge stroke risk. Early diagnosis aids management. Always see a healthcare provider for testing.

Notice fast, fluttering heartbeats (palpitations), shortness of breath, dizziness, or fatigue? These might signal AFib. Reduced ability to exercise could also be a sign. Schedule a checkup soon.

Seek emergency care for chest pain, fainting, severe shortness of breath, or confusion. These may mean a heart attack or stroke. Call 911 right away.

Even without symptoms, routine checkups matter if you have risk factors like high blood pressure. Talk to your doctor about screening.

Maintain a healthy weight and eat heart-friendly foods like fruits, veggies, and whole grains. Manage blood pressure, diabetes, and cholesterol with your doctor's help. These steps may lower AFib risk (NIH).

Get regular moderate exercise, like walking 30 minutes most days, but avoid extremes. Limit alcohol to one drink a day for women and two for men, or less. Quit smoking to protect your heart.

Treat sleep apnea if present and stay active daily. Research suggests these changes might slow progression. Consult a healthcare professional before starting new habits.
