The Actiheart 5 is a wearable, combined single-lead ECG and activity recorder with multiple data endpoints providing a comprehensive personal monitoring device. The latest generation  Actiheart benefits from more than 15 years of research, development and customer feedback to provide a class leading, feature-rich and flexible platform for research in multiple application areas.

The Actiheart 5 provides full waveform, raw data recording of  ECG at up to 1024Hz and tri-axial accelerometry at up to 100Hz. The powerful battery allows long-term recording for up to 14 days in IBI Mode which includes full-waveform acceleration data. The Actiheart 5 replaces both the previous generation Actiheart 4 and the Actiwave Cardio.

The Actiheart uses unique, validated software algorithms based upon a branched model to accurately determine energy expenditure in free-living. The Actiheart has become a benchmark for behavioural research and has been cited in many hundreds of peer-reviewed scientific publications. Our Research Library provides a comprehensive list publications that may be filtered by area of interest.

 

NEW!

The Actiheart 5 may be specified with the latest low-power Bluetooth 5LE wireless module. This provides real-time data streaming to a host PC. The software provides a ‘live view’ of both full ECG and Tri-axial accelerometer data. The Actiheart simultaneously logs the data to its internal memory.

The Actiheart 5 BT is available now – please request a quote.

Wearing the Actiheart

The Actiheart is worn on the chest typically with standard, self-adhesive ECG electrodes or optionally with an elasticated strap. Skin preparation and correct attachment are important factors in overall recording quality.

Energy Expenditure

The Actiheart was originally developed to meet the needs of large scale epidemiological studies where accurate Energy Expenditure in free living was a requirement. Accelerometers alone can provide an indication of MVPA but are limited by deviations in body mounting location and by the type of exercise undertaken by the subject. A classic example of this limitation is during cycling where an accelerometer attached to the wrist or abdomen would severely underestimate energy expenditure because of limited physical movement.

The Actiheart was the first device of its kind to combine Accelerometry with Heart Rate in a single, lightweight, wearable device. The Actiheart software uses a branched model to determine energy expenditure based upon both Accelerometry and Heart Rate for superior accuracy in free-living.

The Actiheart has become a reference device for researchers with hundreds of peer-reviewed publications and multiple validation studies in diverse cohorts.

Heart Rate Variability

It may be commonly assumed that a subject with a heart rate of 60BPM will have a stable heart rhythm equally spread at 1 beat every 1 second. In reality, a physical phenomenen known as Heart Rate Variability (HRV) means that the period between individual beats will vary over time.

HRV provides a very detailed insight into the response of the body’s Autonomic Nervous System to stress and recovery.

By measuring the period between heart beats (know as the Inter Beat Interval or IBI) over long periods, the Actiheart is able to provide researchers with valuable, accurate data for the analysis of HRV.

The Actiheart can record ECG derived IBI for up to 14 days at 1mS resolution and the Actiheart software provides access to the raw data in addition to a range of in built HRV analysis and reporting tools.

Actiheart Software

The Actiheart software package provides a comprehensive solution allowing device set-up, download, data management and analysis functions.

The software is intuitively partitioned into application areas for Energy Expenditure, ECG, HRV, Activity and Sleep Analysis.

The  software has flexible in-built reporting functions and the raw data and all analysis results may be exported.
