Principle

An electrocardiogram (ECG) enables you to observe the regular
sequence of heart contractions as well as to determine your heart
frequency by determining the interval between two heart
contractions. In a second experiment, you will measure the heart
frequencies of test persons of various ages. You can then establish
the fact that the average heart frequency at rest changes when the
body grows.

Benefits


No danger due to electrical energy thanks to wireless operation

Data acquisition with tablets possible

Outdoors and site-independent measurements possible in tablet mode

Wireless measurement mode allows for use in sports medicine

Simple operation of the app, therefore appropriate for all education levels

Long-term measurement possible, i.e. for fitness tests



Tasks


Record an electrocardiogram of your heartbeat at rest and
calculate your resting heart rate

Table 2 shows the heart frequency of people of various age
groups. Describe the age-dependent
differences of the heart frequency and compare the heart frequency
with your own resting heart
rate
