Remote electrocardiograph monitoring using a novel adhesive strip sensor: A pilot study

Figure 3 Representative examples of electrocardiograph strips. A: This strip demonstrates sinus rhythm. All 4 raters scored this strip as having high quality (score 3); B: This strip demonstrates atrial fibrillation. Although the raters quality score ranged from 1 through 3, the irregularly irregular RR interval and absence of discernible P waves present in this Electrocardiograph signal is diagnostic for atrial fibrillation.
