Resumo
Routine laboratory tests depend on the quantitative analysis of various biomarkers and
biochemical parameters in biological samples, in view of this there is a growing search
for biosensors and systems in the form of wearable technologies for use in the
healthcare field, given the scarcity of resources and the widespread use of 12-lead
electrocardiogram (ECG) substitutes, some studies show a good agreement between
the measurement of ECG measured on a smart watch and a 12-lead ECG, therefore
the use of these technologies is promising as health assessment and monitoring
devices. The work had the general objective analyzing the correlation of the RR
intervals of the ECG obtained by the conventional method and by the Apple Watch's
ECG, measuring the RR intervals identified between two QRS complexes selected in
the ECG records, identifying the presence of P waves followed by QRS complex and
finally classifying cardiac rhythms. It was a randomized, cross-sectional study with a
quantitative approach, 20 individuals were selected and invited to participate in this
research, who were approached after a medical consultation with the cardiologist and
to enter the evaluation process they had to have the following inclusion criteria, these
being: healthy, male, aged 20 to 40 years old, no diagnosis of asthma, interstitial lung
disease and cardiovascular or cardiomyopathic impairment, they cannot be using any
type of drugs, all were distributed in only 1 simple random sampling group, Group 1,
which study participants were submitted to the 12-lead ECG exam and immediately
after 30 seconds (s) to the use of the Apple Watch Series 4, to perform the ECG
performed by the brand's own app, the two exams were performed with the participants
lying in the supine position. After applying Pearson's correlation coefficient, a positive
and strong correlation was found, it was also possible to verify the presence of P waves
followed by the QRS complex indicating a conclusion of sinus rhythm. Therefore, it was
possible to verify the correlation between the R-R intervals and the identification of
sinus rhythm by the Apple Watch.
