DST centi-HRT heart rate and temperature logger

The heart rate logger DST centi-HRT simultaneously measures long term heart rate and core temperature in the animal. This makes it ideal for studies in which baseline and immunology responses are recorded. The logger is also suitable for toxicological, metabolic, thermoregulation and hibernation studies.

Examples of Application

Suitable for studies in:

Leadless ECG Derived Heart Rate

The heart rate is derived from a leadless single channel ECG (electrocardiogram) in which the electrodes are part of the housing material, making the logger especially easy to implant. For heart rate the logger takes a burst measurement on any set time interval and calculates the mean heart rate for each recording. Each recorded burst measurement consists of 600 measurements. For validation purposes, each individual burst is graded with a certain QI (quality index) accessible in the accompanying application software.

Suitable for Long-Term Studies

The heart rate logger can store up to 699,000 heart rate and temperature measurements and has a battery life of 19 months (with sampling interval of 10 min at 600 Hz). DST centi-HRT can be easily sterilized and reused as long as the batteries last. Each DST centi-HRT has its own five digit serial number permanently marked on the logger housing as well as placed in the logger's memory and it is provided with all downloaded data. DST centi-HRT is especially useful when a comprehensive data set throughout the research with no disturbance to the animal is needed. Each logger comes with a calibration certificate.

Simple in Use, from Setup to Data Retrieval

The DST centi-HRT is supported by the Mercury software and the Communication Box which serves as an interface between the logger and a PC computer. Communication between the logger and the Communication Box is wireless when logger is placed in the Communication Box.

In the software, the user programs the start time, start date, sampling interval and sampling frequency before the logger is implanted/deployed. Fastest sampling interval is 1 minute but sampling frequency can be varied between 100Hz-800Hz. Optionally, the loggers can be programmed with up to seven different intervals within a measurement sequence. The user defines the number of measurements for each of the interval so it's possible to have more or less frequent measurements during specific periods.

Temperature and heart rate correlation 

Easy Viewing of Data

After recovering the DST, recorded data is uploaded in the software where the results are displayed both in graphic and tabular form. The software also provides the user with some basic statistic information on the data such as minimum and maximum values on defined area, median, average, distribution of values etc. When recorded data has been retrieved, the DST can be re-programmed and reused as long as the batteries last.

A set of Communication Box and Mercury software needs to be purchased with the first order.
