Key result
A smartphone-case based ECG monitor with photoplethysmography correlated strongly with a conventional sphygmomanometer for measuring systolic (r=0.89, p=0.001) and diastolic (r=0.87, p=0.002) BP.
Why the study?
Simple, accurate, and affordable cuffless blood pressure devices could enhance compliance with measurement recommendations and telemonitoring, prompting evaluation of a smartphone-case ECG and photoplethysmography device in hypertensive patients.
Does a smartphone-case based ECG monitor with PPG accurately measure blood pressure compared to a conventional sphygmomanometer in hypertensive patients?
Population
500 patients aged 32–88 years with arterial hypertension

Does a smartphone-case based ECG monitor with PPG accurately measure blood pressure compared to a conventional sphygmomanometer in hypertensive patients?
Effect estimate: r=0.89 for systolic, r=0.87 for diastolic
p-value: p=0.001 for systolic, 0.002 for diastolic
A smartphone-case based cuffless blood pressure monitor using ECG and PPG demonstrated strong correlation with conventional sphygmomanometry, highlighting its potential for accessible BP telemonitoring.
Sagirova et al. (2021) conducted a cross-sectional in Arterial hypertension (n=500). Smartphone-case based single-channel ECG monitor with photoplethysmography vs. Conventional sphygmomanometer was evaluated on Correlation of systolic and diastolic blood pressure between the cuffless method and sphygmomanometer (r=0.89 for systolic, r=0.87 for diastolic, p=0.001 for systolic, 0.002 for diastolic). A smartphone-case based ECG monitor with photoplethysmography correlated strongly with a conventional sphygmomanometer for measuring systolic (r=0.89, p=0.001) and diastolic (r=0.87, p=0.002) BP.
