Describe the behavior of the frog heart that you can elucidate from the force recording (e.g., mechanical events). How can you u

Sladkaya [172]

Answer:

P wave and R wave

Atrial contraction = P wave

Ventricular contraction = R wave

Explanation:

The behavior of the frog heart from force recording can be classified into ; P wave and R wave.

utilizing the ECG ( Electrocardiogram) data the aspect of the force recording that is due to atrial contractions is the ; P wave while the force recording that is due to ventricular contractions is the ; R wave the ventricular contractions is also known as QRS

ECG is used to record the electrical activities of a heart at rest
