Cardio Main Features • Record a full single channel ECG Waveform for up to 31 hours • Simultaneously record 3-axes of acceleration • Combine heart rate and activity to calculate energy expenditure – validated against Doubly Labelled Water • Use acceleration data to record body position • Non-invasive technology • Compact and light-weight • Non-volatile memory • Rechargeable The Actiwave Cardio is a waterproof ultra-miniature single channel ECG waveform recorder. It consists of two electrodes connected by a short lead which simply clip onto two standard ECG pads worn on the chest. It also contains a tri-axial accelerometer, the signal from which allows the user to determine resting body position. For a single channel 24 hour holter recording the Actiwave Cardio gives unsurpassable wearability. The very small size allows for continuous monitoring in a wide range of patients and applications. ECG recording with the Actiwave Cardio The Cardio is ideally suited for Heart Rate Variability (HRV) and Inter-beat Interval (IBI) measurements in ambulatory settings. The Cardio measures the ECG waveform and 3-axes of acceleration. The data is transferred to the Cardio Viewer software (or can be exported to 3rd party software as EDF+ les) which performs the Heart Rate Variability analysis. Some selected statistics available include: Average IBI: Average Inter-beat Interval (IBI) for the analysis epoch Standard Dev: Standard Deviation of the IBI data Min & Max IBI: Minimum and maximum IBI in the epoch VLF, LF, HF: The very low, low & high frequency component of the IBI, derived using an FFT RMSSD: The Root Mean Square Successive Difference: a time domain measure of HRV Position: The position of the subject’s body calculated using the accelerometer Rotation: The rotation of the Cardio Energy expenditure The Cardio is an ideal device for measuring energy expenditure in free living for short periods of time. The following parameters are provided: RMR: Resting metabolic rate AEE: Activity Energy Expenditure TEE: Total Energy Expenditure Technical Specication ECG Range: Impedance: Frequency: Acceleration Range: Frequency: Bibliography Elbaz, M.
