Key result
Smartphone-integrated Sinabro system detects QRS peaks with >96% accuracy during routine use.
Why the study?
Can a smartphone-integrated opportunistic ECG monitoring system reliably capture ECG signals and accurately extract HRV features during daily smartphone use?
Can a smartphone-integrated opportunistic ECG monitoring system reliably capture ECG signals and accurately extract HRV features during daily smartphone use?
Sinabro enables unobtrusive, reliable ECG and HRV monitoring opportunistically during daily smartphone use, demonstrating feasibility for pervasive digital healthcare applications.
May support unobtrusive daily ECG/HRV monitoring; leaves open clinical utility pending prospective validation.
In our preliminary study, we proposed a smartphone-integrated, unobtrusive electrocardiogram (ECG) monitoring system, Sinabro, which monitors a user's ECG opportunistically during daily smartphone use without explicit user intervention. The proposed system also monitors ECG-derived features, such as heart rate (HR) and heart rate variability (HRV), to support the pervasive healthcare apps for smartphones based on the user's high-level contexts, such as stress and affective state levels. In this study, we have extended the Sinabro system by: (1) upgrading the sensor device; (2) improving the feature extraction process; and (3) evaluating extensions of the system. We evaluated these extensions with a good set of algorithm parameters that were suggested based on empirical analyses. The results showed that the system could capture ECG reliably and extract highly accurate ECG-derived features with a reasonable rate of data drop during the user's daily smartphone use.

Kwon et al. (2016) studied this question. Sinabro smartphone-integrated ECG monitoring system vs. Conventional ECG acquisition system (BIOPAC MP150) was evaluated on Reliability of ECG capture (QRS peak detection ratio) and accuracy of HRV feature extraction. The Sinabro system captured ECG reliably during daily smartphone use, with QRS peak detection ratios >96% in portrait modes and an average error of 5.6% for HRV parameters.
