Cardiographie sous effort physique, avec Cobra4

Numéro d´article: 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.

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

  1. Record an ECG while switching from rest to strain (20 squats)
  2. Record an ECG while switching from strain to rest and calculate the time that elapses until the resting heart rate is reached again

What you can learn about

  • Electrocardiogram (ECG)
  • Cardiac activity
  • Heart muscle
