Paroxysmal Atrial Fibrillation (PAF)
Paroxysmal Atrial Fibrillation (PAF): Everything You Need to Know
Paroxysmal atrial fibrillation (PAF) is a type of heart rhythm disorder (arrhythmia) where the heart does not beat correctly. It is characterized by irregular and rapid heartbeats originating from the upper chambers (atria) of the heart. During PAF, the heart rate can reach up to 160 to 175 beats per minute, but can slow down to a normal level with no treatment. In some cases, PAF may be preceded by an episode of palpitations, chest pain, angina, dizziness, and/or syncope (fainting).
PAF affects an estimated 2 percent to 4 percent of adults and is more common in men than women. It’s also more common in those over the age of 65. Individuals with high blood pressure, abnormal heart valves, heart failure, or those who have had a heart attack are more likely to experience PAF.
Symptoms of PAF include:
- Irregular heartbeat
- Palpitations
- Chest pain
- Angina
- Lightheadedness or dizziness
- Shortness of breath
- Fatigue
PAF may be asymptomatic; however, when symptoms are present, they can be treated with medications or procedures such as ablation. Medications used to treat PAF include beta blockers, calcium channel blockers, antiarrhythmic drugs, and others.
It’s important to note that PAF can be dangerous and can cause stroke, heart failure, and even death. If you experience any of the symptoms mentioned, it’s important to seek prompt medical attention. Your doctor will work with you to create an individualized treatment plan that best suits your needs.
