Diagnostic Tests

1.Electrocardiogram

  • AF is a supraventricular tachyarrhythmia with uncoordinated atrial activation and consequently ineffective contraction with ECG characteristics of:
    • Irregular R-R intervals (when AV conduction is present)
    • Absence of distinct, repeating P waves
    • Irregular atrial activity

2. Blood Tests

  • helps with identification of blood substances related to comorbidities that may lead to AF

3. Holter Monitor

  • small, portable ECG devise that records the heart’s activity for 24 hours
  • determinant for AF

4. Echocardiogram

  • noninvasive test using sound waves to create images of the heart’s size, structure, and motion

5. Stress Test

  • exercise testing determines the capacity of the heart to function without tachycardia
  • determinant for AF

6. Chest X-ray

  • identifies the condition of the lungs and heart

Treatment & Management

  • Initial step: determine the most suitable course of treatment. Understand the:
  • AF duration
  • AF classification
  • Onset date
  • Date of AF discovery, frequency
  • Contributory risk factors
  • Symptoms
