Information People Need to Know about Atrial Fibrillation

Based on reports from the medical sector, an estimated five million Americans are living with atrial fibrillation right now. Many studies show that this condition has become far more common over the years than it was in the past. While some experts believe it’s simply being diagnosed more often now, others attribute the ongoing uptick to an aging population. Either way, more people are suffering from afib. Because of that, it’s becoming increasingly important that those living with the condition and their families fully understand it.

Understanding Afib

In light of the increasing prevalence of this condition, a growing number of people are now asking, “What is AFib?” In short, it’s a condition that’s characterized by an irregular heartbeat. Normally, the heart’s upper and lower chambers, the atria and ventricles, contract in sequence. First, the upper chambers contract; then, the lower ones follow suit. That pushes blood through the heart and the rest of the body.

For those with AFib, the process doesn’t quite work the way it should. Instead, the atria can beat irregularly and often extremely rapidly. That hampers normal blood flow. Additionally, it may cause blood to pool in the heart. That increases the risk of blood clots. In turn, it increases the risk of stroke, heart failure, and other serious issues. While afib has been known to affect people of all ages, it’s particularly common in older adults.

What Causes Afib?

Atrial Fibrillation stems from irregular electrical signals telling the upper chambers of the heart when and how to contract. Those signals travel through the sinus node, which acts as a natural pacemaker. With afib, the electrical signals become hectic as opposed to regular and consistent. That interruption also prevents electrical signals from making their way to the ventricles, telling them when to contract.

Irregular electrical signals to the heart can come from many sources. Heart attacks, valve defects, and other cardiac problems are common causes of afib. High blood pressure, thyroid issues, and certain viral infections can also increase a person’s risk of afib. Excessive use of stimulants can lead to this type of arrhythmia as well.

Dealing with Afib

Medications are the most common treatments for afib. Some are designed to slow the heart rate to combat rapid, irregular electrical signals. Others are blood thinners that reduce the risk of developing blood clots that can lead to other issues. In some cases, patients with afib may need more in-depth treatment. That may include placing a catheter into the heart or other surgical procedures.
