We determine our heart frequency with Cobra SMARTsense

Principle

With the help of an electrocardiogram (ECG) you can follow the regular sequence of heart contractions and determine the heart rate by determining the time interval between two heart contractions. In a second attempt, the heart rate of test persons of different ages is measured and it can be shown that, as the human body grows, its average heart rate changes at rest.

Benefits

• Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
• Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
• Increased motivation of students by using the intuitive measureAPP.
• Increased media competence.

Tasks

• Prepare an electrocardiogram of your heartbeat at rest and calculate your heart rate at rest
• Describe the age-related differences in heart rate and compare it to your own heart rate at rest

Learning Objectives

• Electrocardiogram
