Item no.: P1522160
Principle
An electrocardiogram (ECG) can record the sum of the electrical activities of all of the heart muscle fibres. Under stress, cardiac activity increases in order to maintain the stability of the cardiovascular system. The heart contraction cannot be controlled at will. This experiment enables you to study how physical stress affects the respective activity of your heart.
Tasks
- Record an ECG while switching from rest to strain (20 squats)
- Record an ECG while switching from strain to rest and calculate the time that elapses until the resting heart rate is reached again
