A Quick Guide to AFIB


What is Atrial Fibrillation (AFib)?

  • Atrial fibrillation, or AFib, is an irregular and rapid heartbeat that causes the heart's upper chambers to quiver.
  • This condition affects millions of people worldwide, and it can lead to serious health problems like stroke and heart failure.

Risk Factors and Triggers of AFib

  • Various factors contribute to AFIB risk, including age, hypertension, obesity, and sleep apnea.
  • Some substances and infections, like alcohol and the flu, can also trigger AFib.
  • Managing these factors is crucial in reducing AFIB risk.

Symptoms of Atrial Fibrillation

  • AFib often goes unnoticed, but some may experience palpitations, dizziness, chest pain, anxiety, depression, sleep problems, and fatigue.
  • Unfortunately, many people discover they have AFib only after experiencing a stroke.

Types of Atrial Fibrillation

  • AFib can be categorized by its duration:
    • Paroxysmal AFib occurs occasionally and stops within seven days.
    • Persistent AFib lasts more than seven days, up to a year.
    • Long-standing persistent AFib persists for more than a year.

What Is Your Risk for AFib?

  • AFib can cause lasting damage to your heart and brain.
  • A risk assessment tool can help estimate your risk of having or developing AFib.
  • Consult a specialist if you're at medium or high risk.

Do You Have AFib?

  • You can check for AFib by monitoring your pulse manually or using smartphone apps or home blood pressure monitors.
  • If you suspect AFib, consult a healthcare professional for an accurate diagnosis.

AFib Risk Evaluation and Diagnosis

  • Diagnosis involves evaluating symptoms, risk factors, and medical history.
  • Tests like EKG, echocardiogram, and blood tests help confirm AFib.
  • Proper diagnosis is essential to determine the best treatment approach.

Atrial Fibrillation and Stroke

  • Did you know that AFib increases the risk of stroke by five times?
  • Several factors, including age, hypertension, and heart failure, can further elevate this risk.
  • During AFib, blood can clot in the heart, potentially leading to a stroke if the clot travels to the brain.

Atrial Fibrillation and Heart Failure

  • AFib and heart failure are interconnected heart conditions.
  • Heart failure can weaken the heart muscles, and AFib's irregular rhythms put extra stress on the heart.
  • Treating AFib can improve heart function and, conversely, heart failure can lead to AFib.

Atrial Fibrillation and Sleep Apnea

  • People with sleep apnea are four times more likely to develop AFib.
  • Sleep apnea, a condition where breathing repeatedly stops and starts during sleep, can increase the risk of heart disease.
  • Identifying and treating sleep apnea can help manage AFib better.

Atrial Fibrillation and Influenza (Flu)

  • Influenza (flu) can raise the risk of heart attacks, strokes, and AFib.
  • Getting an annual flu vaccine can help prevent this trigger for AFib.

AFIB Treatment in Houston, TX

  • Treatment focuses on risk factor modification, stroke prevention, heart rate control, and rhythm management.
  • Medications, catheter ablation, cardioversion, and pacemakers are among the available treatments.
  • Lifestyle changes and managing risk factors are crucial in AFib management.

Living with Atrial Fibrillation (AFib)

  • Taking an active role in your care can improve your quality of life.
  • Communicate openly with your doctor about symptoms, medications, and lifestyle changes.
  • Lifestyle modifications, stress management, and regular follow-ups are key to managing AFib.

What Should I Ask My Doctor If I Have AFib?

  • Prepare a list of questions for your doctor to understand your condition better.
  • Questions may cover causes, types, symptoms, treatment options, and lifestyle adjustments.
  • Being informed empowers you to make the best decisions for your AFIB management.
