Comparison of Time‐Domain Short‐Term Heart Interval Variability Analysis Using a Wrist‐Worn Heart Rate Monitor and the Conventional Electrocardiogram

Abstract: Background: Wrist-worn heart rate monitors have not been extensively validated for heart rate variability analysis. The purpose of this study was to compare time-domain variability of heart interval series (R-Ri) recorded by the Polar S810 monitor (Polar Electro Oy, Kempele, Finland) 02). The SDNN, CV, and pNN50 indices did not show differences (P = 0.12 to 0.73). Conclusions: The Polar S810 monitor was feasible and reliable for recording short-term R-R interval series, showing excellent agreement with the… Show more

“…In our study the Polar RS400 had a good criterion-related validity, which is in agreement with previous studies of Polar S810, Polar S810i and Polar Vantage XL and ECG (4)(5)(6)(7)(8)(9). The correlation-coefficient is very high at both 50 and 100W and is 1.0 at 150 W. This indicates that the measurement of HR with Polar RS400 is as reliable as with ECG.…”

“…Data were then visually inspected and any remaining 'spikes' in the data were removed and replaced with the next appropriate RR interval. The detection of RR intervals using similar Polar heart rate technology has been validated against 12-lead ECGs (19) however, there is uncertainty regarding the ability of the PPT5's error correction function to detect non-sinus originating beats which can result in inflated results (29). Therefore, all data were screened for outliers using the Median Absolute Deviation (30), and participants with greater or less than 3 × the population standard deviation as estimated by the median (17) were excluded from the data.…”

“…Sin embargo, recientes estudios [22][23][24] vienen demostrando la eficacia y aplicabilidad de este dispositivo en el análisis de los índices de variabilidad de la FC, tanto en el dominio del tiempo como en el dominio de la frecuencia, posibilitando así una evaluación fidedigna, de bajo costo y no invasiva del balance autonómico. A pesar de tratarse de métodos de evaluación diferentes, tanto el IVC obtenido a través del T4s como los índices adoptados para análisis de la VFC advienen de la medición del intervalo RR, lo que nos permite asociar los resultados encontrados en los estudios citados anteriormente.…”
