See your doctor if you experience these symptoms: irregular heartbeat, palpitations (a feeling your heart is fluttering or racing), shortness of breath, dizziness, chest pain, or unexplained fatigue. These may indicate atrial fibrillation.
Diagnosis involves several steps:
Physical Exam: Your doctor will listen to your heart with a stethoscope, checking for irregular rhythms. Electrocardiogram (ECG or EKG): This test records your heart’s electrical activity. An ECG clearly shows atrial fibrillation’s characteristic irregular heartbeat. Holter Monitor: This portable device records your heart rhythm continuously for 24-48 hours, detecting fibrillation episodes that may not be present during a single ECG. Event Recorder: If infrequent episodes are suspected, this device is worn for weeks or months, only recording when you activate it by pressing a button when experiencing symptoms. Echocardiogram: This ultrasound test images your heart, assessing its structure and function to rule out other conditions and evaluate the severity of the AFib.
Understanding your risk factors is also crucial. These include:
- High blood pressure Heart valve disease Diabetes Obesity Smoking Excessive alcohol consumption Age (risk increases with age) Family history of atrial fibrillation
Early diagnosis and management are key to preventing complications. Discuss your symptoms and risk factors with your physician to determine the best course of action.
