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
