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.
