Heart palpitations? Shortness of breath? You could have AFib.

The rhythm change may begin slowly, but can become stronger and more consistent as time goes on. It is the most common type of arrhythmia and may increase risk of blood clots, stroke, heart failure and other heart-related complications.  Typically, a normal resting heart rate doesn’t exceed 100 beats per minute. For those with AFib, their heartbeat can reach as high as 175 beats per minute.

AFib does not always present with symptoms and many people do not know they have it. However, those who do can experience one or more of the following:

  • Feeling faint
  • Shortness of breath
  • Extreme fatigue
  • Chest pain
  • Heart palpitations

According to the American Heart Association, nearly 3 million people in the U.S. have AFib, and it affects more than 9 percent of people aged 65 years and older.

Why Is It Dangerous?

AFib can cause blood to pool in the heart’s left atrial appendage, which can create clots. Those clots can travel through the bloodstream, blocking the flow of blood to the brain and causing a stroke. 

When a person has heart palpitations, an electrocardiogram (EKG) is usually ordered and the patient may wear a Holter monitor for 24 to 48 hours to record heart activity. But because abnormal heart rhythms come and go, there is a chance arrhythmia will not be detected through these tests that only capture heart rhythms for a short period of time.

Causes and Treatment for AFib

As people age, certain health conditions can put them at risk for AFib, including high blood pressure, diabetes, obesity, sleep apnea, heart failure and smoking. Once detected, medication is usually a first-line treatment option. Depending on the severity of the case, cardiac ablation (the scarring of heart tissue to block abnormal electrical signals) or inserting a pacemaker can also be effective.
