Hi and welcome to the forum! I am glad that I can help you.
You would like to know whether according to the doctor's report you might have experienced atrial fibrillation.
Atrial fibrillation is cardiac arrhythmia that involves the two upper chambers (atria) of the heart. Its name comes from the fibrillating (i.e. quivering) of the heart muscles of the atria, instead of a coordinated contraction. Atrial fibrillation is often asymptomatic, but may sometimes be characterized with palpitations, fainting, chest pain, or congestive heart failure. People with AF usually have a significantly increased risk of stroke because blood may pool and form clots in the poorly contracting atria. It is diagnosed with ECG or Holter (a 24 hour recorded ECG scan). Cardiologists recognize the irregularities in the heart rhythm based on the Holter scan and mark them with abbreviations including AFIB for atrial fibrillation.
Given the data that you described, it seems likely that you may have experienced an episode of atrial fibrillation. You may consider seeing a cardiologist for further advice and information about treatment options.
