The Cardio
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 making the Cardio ideal for use in investigating sleep disorders such as Obstructive Sleep Apnoea (OSA). 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.
The Cardio offers short period waveform recording at greater resolution than the Actiheart, alongside the three axis accelerometry data. It opens wider possibilities in short term recording and waveform data analysis, but without the Actiheart's strong focus on longer term recording and energy expenditure. Both are capable of capturing data for Heart Rate Variability (HRV) analysis. Please read the application note below or contact us if you need more guidance between the two.
Applications
- ECG 24 hour Holter recordings
- Suitable for adult or paediatric use - shorter leads available
- Truly free living recordings of ECG
- Epidemiology
- Ideal for veterinary applications
The Cardio is also an integrated part of the Actiwave range, using the same PC software and range of docks.

The sampling frequency can be varied for both the ECG and accelerometry capture, and up to 10 bit resolution is available. The recording time specified above refers to 128Hz ECG recording alongside 32Hz acceleration, with 8 bits recorded. The ECG signal can also be resampled on download to a different rate, if required for compatibility with existing software.
CamNtech also supplies a range of docking stations. These units are used to interface with the PC software and both charge and initialise/download the Actiwave range. The options suitable for the cardio are shown below:
