Telemetric heart rate monitoring in free-ranging marmots (Sciuridae)

Local Knowledge Graph (7 entities)

Description

Surgical implantation of radio transmitters in the abdominal cavity with electrodes positioned on either side of the heart to monitor heart rate via radio telemetry during natural behaviors. Heart rate data is collected remotely and converted from interpulse intervals to beats per minute.

Typical Equipment

• Heart-rate radio transmitters (Telonics)
• Telonics TR-1-20 receiver
• Telonics TDP-2 digital data processor

Output Measurements

• heart rate (beats per minute)
• interpulse intervals (milliseconds)
