Atrial Fibrillation Diagnosis

If screening tests or check-ups reveal abnormal results, your WellStar Cardiac Network Physician may perform further evaluations to focus on atrial fibrillation.

Procedures

• Electrocardiogram: An ECG (or EKG) records the electrical activity of your heart to reveal if there are rhythmic issues or heart injury.
• Echocardiogram: This test uses sound waves to produce images of the heart that can show structural heart disease.
• Holter monitor: This portable electrocardiogram monitor is worn for 24 hours and tracks your heart rhythm during a day of your regular activities. This is often necessary in cases where atrial fibrillation starts and stops.
• Event recorder: This monitor is worn for a longer period, sometimes as long as one month, to detect heart rhythm disturbances that occur at unpredictable times.
• Transesophageal echocardiogram: This test may reveal if blood clots are present in the top chambers of the heart.
