Abstract

Introduction: Atrial fibrillation increases cardiovascular mortality and morbidity.


The study was aimed to determine the possibility of application of the Polar H7 Heart Rate Sensor in assessment of heart rate in people with sinus rhythm. Results will be used to construct an algorithm, which would detect a silent atrial fibrillation using the Polar H7 Heart Rate Sensor.


Materials and methods: This prospective analysis study was conducted in a group of 15 healthy individuals (8 females, 7 males) aged of 22 ± 1,3 years with sinus heart rhythm. Heart rate was recorded simultaneously with ECG (CNSystems, Medizintechnik, Graz, Austria) and H7 Heart Rate Sensor (Polar Electro, Kempele, Finland). One hundred and fifty 30-second-long intervals recorded by both devices were compared in the terms to the agreement of the heart rate and heart rate variability. Variability of heart rate was defined as a standard deviation. Bland-Altman statistics were used in the analysis.


Results: We found good agreement between ECG and Polar H7 in assessment of mean heart rate: bias 0.37 with limits of agreement: -1.66 to 2.40. Worse agreement was observed according to heart rate variability: bias 2.52 with limits of agreement: 0.59–5.54.


Conclusion: Polar H7 Heart Rate Sensor showed a good agreement with reference method determining an mean heart rate in 30 second-long intervals. In terms of assessment of heart rate variability good enough compliance was not observed. Polar H7 Heart Rate Sensor can be used to assess mean heart rate in people with sinus rhythm at rest.
