Polar S810 como recurso alternativo ao eletrocardiograma no teste de exercício de 4 segundos

Abstract: ResumenFundamento: El test de ejercicio de 4 segundos (T4s) evalúa el tono vagal cardíaco durante el transiente inicial de la frecuencia cardíaca (FC), en ejercicio dinámico súbito, por medio de la identificación del índice vagal cardíaco (IVC) obtenido a partir del electrocardiograma (ECG).Objetivo: Probar la utilización del monitor de frecuencia cardiaca (MFC) Polar S810 como recurso alternativo al ECG en la aplicación del T4s.Métodos: En este trabajo, 49 individuos del sexo masculino (25 ± 20 años, 176 ±12 … Show more

“…The literature show that R-R interval (period between two successive R waves in the ECG) data samples with 5 minutes of duration, obtained with HR monitors, can be used for HRV analysis 29,30 . Some studies have already shown that HRV analysis, i.e., frequency domain, performed on data sampled with HR monitors over a short period (short-term) or with ECG devices over a long period (long-term), produces comparable and accurate results [31][32][33][34] . In addition, Pimentel et al 34 showed that HR monitors can be used for R-R interval sampling during exercise, a condition marked by pronounced changes in the sympathovagal balance.…”
