Recording of Bipolar Multichannel ECGs by a Smartwatch: Modern ECG Diagnostic 100 Years after Einthoven
Why the study?
The study evaluated the feasibility of recording accurate three-lead ECGs (Einthoven I, II, and III) using an Apple Watch Series 4.
Does recording three bipolar ECGs using an Apple Watch Series 4 provide accurate Einthoven leads I-III comparable to a standard 12-lead ECG in healthy subjects?
Population
50 healthy subjects without known cardiac disorders

Implication
Apple Watch three-lead ECG is feasible in healthy volunteers; leaves open validation and utility in cardiac patients.
Structured PICO
Does recording three bipolar ECGs using an Apple Watch Series 4 provide accurate Einthoven leads I-III comparable to a standard 12-lead ECG in healthy subjects?
P
Population
50 healthy subjects without known cardiac disorders, mean age 40 ± 12 years, 18 male.
I
Intervention
Three bipolar ECGs (Einthoven leads I, II and III) recorded using an Apple Watch Series 4 placed on different body positions.
C
Comparator
Standard 12-lead ECG.
O
Outcome
Correct assignment of watch ECGs to corresponding Einthoven leads from 12-lead ECG by four independent cardiologists.surrogate
An Apple Watch Series 4 can accurately record three bipolar ECGs corresponding to Einthoven leads I, II, and III, which are highly comparable to a standard 12-lead ECG.
