Follow the procedure on this site to record and measure change in heart rate (ECG) from a human after immersing in cold water. Next, design an experiement to identify the exact stimulus that evokes the change in heart rate (in beats per minute or BPM).
To record the change in heart rate that occurs when a subject immerses his face in cold water.
To investigate the physiological reason for the observed response.
Tasks Performed by the Student
Subject will submerge face in cold water during breath holding (apnea).
Add event markers throughout the recording.
The software automates the calibration procedure for the student. There are no knobs and dials to confuse the student.
Graph template files ensure consistent setup for subsequent Subjects or repeated trials—plus, you can easily add your own lesson plan to the onscreen journal.
>The lesson will also work as part of a group study.
