The heartbeat is controlled by electrical impulses that begin in the atria, or upper chamber of your heart.; In AFib, these electrical impulses are erratic, causing a rapid and irregular heartbeat that affects the heart's ability to pump blood efficiently to the rest of the body.
Symptoms of AFib Include:
- Irregular or rapid pulse or heartbeat
- Dizziness, sensation of light-headedness
- Sensation of your heart fluttering (palpitations)
- Sensation of missed or extra heartbeat
- Shortness of breath
Some people may not experience symptoms while others may have noticeable symptoms.
Treatments for AFib
- Antiarrhythmic medications
- Electrical cardioversion or defibrillation
- Automatic implantable defibrillator
- Artificial pacemaker
- Catheter ablation
- Surgical intervention
If AFib or any arrhythmia is left untreated, it can lead to stroke or heart failure.
