Actiheart
2Pages

Main Features • Recording of physical activity by means of an accelerometer • Recording of heart rate synchronously with activity • Displaying time domain variability of the R-R Interbeat Interval (IBI) • Frequency domain analysis of the IBI data • Calculation of energy intensity during physical activity • Derivation of individual HR-V02 relationship using built in Step Test or utilisation of externally derived calibration data • Calculation of energy expenditure in daily living (validated against doubly labelled water) • Data is stored in a database and is fully exportable for manipulation in third party programs The Actiheart is the rst truly light-weight (10gm) and waterproof self contained logging device which allows physical activity to be recorded synchronously with heart rate. The Actiheart is worn on the chest. It consists of two electrodes connected by a short lead which simply clip onto two standard ECG pads. Being self contained, it is comfortable to wear for ambulatory activity and heart rate recording. The Actiheart contains a battery which is recharged via a purpose built USB interface. Power can be taken from the PC or from an external power supply which is provided. This interface also allows data transfer to the PC for setting up the Actiheart and analysing the data using custom software. The raw data is held in a database and can be edited with full traceability without compromising the integrity of the original Technical Specication data. Data can also be exported for manipulation Waterproof: Yes in third party programs. Memory: 512 KB Energy Expenditure The analysis software contains a model for Battery : Rechargeable calculating energy expenditure using differentially Battery life: 21 days weighted activity and heart rate data.1 Weight: 10 grams Validation Size: 32mm dia. The reliability and validity of the product for 6mm depth recording activity and heart rate as well as the Warranty: 2 years measurement of energy expenditure have been (Excludes cable damage) 2 scientically validated. PC Analysis: Windows® Applications XP/Vista The Actiheart is ideal for use in the eld of sports Windows®7 and exercise science, stress, obesity and other epidemiological applications. For situations where the Actiheart cannot be worn on ECG pads, we are also able to offer a chest band. This is ideal for sports science applications and other similar short wear periods during activity. Bibliography 1.
