The rhythm shown on this page of your Holter monitor is sinus rhythm, not atrial fibrillation (AF).
Key observations from the strip:
• Regular P waves are clearly visible before every QRS complex (best seen in the lead with upright P waves).
• PR interval is consistent and normal (~120–160 ms).
• QRS complexes are narrow and regular.
• The rhythm is fairly regular at a rate of ~90–100 bpm (calculated from the scale: 25 mm/sec paper speed, ~25–30 small boxes between R-R intervals).
• There are occasional slight irregularities in R-R interval, but these are sinus arrhythmia (normal physiological variation, especially common in young adults) or respiratory variation — not AF.
• No absent P waves, no irregularly irregular R-R intervals, no fibrillatory baseline — all hallmarks of AF are absent.
This is normal sinus rhythm with possible mild sinus arrhythmia (heart rate variation with breathing) — completely benign at your age (26 years male) and not AF or any dangerous arrhythmia.
Next Steps
• This single page looks reassuring — no AF or significant arrhythmia visible.
• However, Holter reports are interpreted by looking at the full 24–48 hour recording, not just one page. The final report (summary) from the cardiologist is what matters most.
• If the official Holter report (the typed summary at the end) says “normal sinus rhythm” or “sinus rhythm with occasional ventricular ectopics / sinus arrhythmia” → you are fine.
• If the report mentions AF, frequent ectopics, or pauses → then follow up with the cardiologist.
Health Tips
• Do not panic from looking at one strip — Holter tracings can look alarming to non-experts, but trained cardiologists read the entire recording.
• Ask your cardiologist / the lab for the final typed Holter report summary (usually 1–2 pages at the end) — that will clearly state the rhythm diagnosis.
• If you have palpitations, dizziness, chest pain, or syncope episodes → share the full Holter report with the cardiologist for correlation.
• Continue normal life — this page alone does not show AF or anything dangerous.
For complete peace of mind (review of the full Holter report if you have the typed summary, explanation of any ectopics/pauses if present, when to worry, or lifestyle advice to reduce palpitations), please book an online consultation with me — I’ll look at the complete report (or the summary page) and give you a clear, reassuring explanation tailored to your symptoms.
You are most likely fine — let’s confirm it together and remove the worry
