Table 3. Comparison of signal loss and noise between novel telemonitoring system using a single-lead ECG patch and the conventional telemonitoring system.

Variables	Novel telemonitoring system*	Conventional telemonitoring system†	p value for difference
Proportion of noise data‡ (%)	0.3 (0.1–1.6)	2.4 (1.4–3.7)	<0.001
Episodes of signal loss§ (N)	22 (2–53)	64 (22–112)	0.002
Minimum duration of signal loss (sec)	0.5 (0.5–0.6)	0.5 (0.5–0.6)	0.325
Maximum duration of signal loss (sec)	4.5 (2.5–5.1)	4.5 (4.1–4.9)	0.064

Data are presented as median (interquartile range).

^‡Most noise data were due to signal noise from motion artifacts or poor contact between electrodes and skin. The noise data excluded the episodes with signal loss.

^§Most episodes of signal loss were due to transient loss of wireless connection due to participants wandering outside the effective range of the AP.

AP = access point; ECG = electrocardiogram.
