Small, Implantable Heart Rate and Temperature Data Logger

Small, leadless, minimally invasive and easy to implant. Long term heart rate and body temperature.

Ideal for long- and short term studies in which baseline, stress and immunology responses are recorded in small animals.

Key features

  • Leadless, minimally invasive
  • Small size- only 3.3g
  • Long battery life – typically over 3 months
  • Automatic stress-free measurements
  • ECG derived heart rate, including data verification
  • Description

    Leadless, Minimally Invasive

    The DST micro-HRT simultaneously measures long term heart rate and temperature in the study animal. The logger has no external wires, which makes it especially simple to implant and is made of unique ceramic housing and epoxy and is hermetically sealed, guaranteeing biocompatibility.

    Application

    The logger is ideal for a variety of studies including those looking at behaviour and stress response, in the fields of laboratory animal research, wildlife research, animal welfare and fish physiology.

    Leadless ECG Derived Heart Rate

    The heart rate is derived from a leadless single channel ECG. As the electrodes are part of the housing the logger is especially easy to implant. The logger takes a burst measurement of ECG at the set time interval and calculates the mean heart rate for each recording. For validation purposes, individual ECG bursts can be saved. In addition each burst is graded with a QI (quality index).

    Stress-Free Long-Term Studies

    The logger is especially useful when a comprehensive data set throughout the research is needed with no disturbance to the animal. The heart rate logger has a battery life of over 3  months, with sampling interval of 10 minutes.

    Single or multiple intervals

    There are two modes for sampling, either at a single interval throughout the period or multiple intervals. Multiple intervals are especially useful when frequent measurements are needed at certain time periods.
