Understanding Atrial Fibrillation: Causes, Symptoms, and Management

What is Atrial Fibrillation?

Atrial fibrillation (AFib) is a common heart rhythm disorder marked by irregular and rapid heartbeats. Normally, the heart's chambers beat in sync, but AFib disrupts this rhythm, requiring treatments aimed at restoring normal heartbeat. These interventions include medications or procedures, from minimally invasive methods to open-heart surgeries.

Primary Causes of AFib

Genetic predisposition can increase risk.

Valve-related heart diseases may cause irregular rhythm.

High blood pressure is a significant contributing factor.

Infections, thyroid issues, and metabolic conditions can also lead to AFib.

Factors Increasing Risk

Respiratory problems such as COPD and sleep apnea raise susceptibility.

Conditions like diabetes and obesity are linked to higher risk.

Pre-existing heart conditions, including heart failure and coronary artery disease, are common underlying causes.

People over 60 are more prone to develop AFib.

Signs and Symptoms

Irregular heartbeat often causes palpitations or discomfort.

Fatigue and weakness are prevalent symptoms.

Dizziness, lightheadedness, and brief confusion may occur.

Shortness of breath, chest discomfort, and sweating are also typical.

Diagnostic Approaches

Medical history review and physical exam are initial steps.

Symptom monitoring provides valuable clues.

An ECG is essential for diagnosis.

Additional tests include echocardiograms, chest imaging, and stress tests.

Blood tests can help identify thyroid or metabolic contributors.

Common Treatment Methods

The primary goal is to restore a normal rhythm.

Electrical cardioversion resets heartbeats using shocks.

Catheter ablation eliminates abnormal tissue causing arrhythmia.

Surgical maze procedures create scar tissue to guide electrical signals properly.

AV node ablation modifies electrical pathways to control rhythm.

Medications for AFib

Blood thinners reduce stroke risk by preventing clot formation.

Antiarrhythmic drugs help restore normal heart rhythm.

Heart rate control medications manage irregular beats.

Preventive Measures

Regular exercise supports heart health and weight management.

A heart-healthy diet low in saturated fats, salt, and cholesterol is recommended.

Avoid smoking, excess alcohol, and caffeine.

Controlling blood pressure and cholesterol levels is essential for prevention.
