Question Answered step-by-step A frog heart was stimulated w/ a grass simulator (1Hz, 20Vots) on… A frog heart was stimulated w/ a grass simulator (1Hz, 20Vots) on repeat mode. How is the contraction amplitude change as a function of the stimulus frequency? What is the difference between the refractory period of cardiac muscle and skeletal muscle? What mechanism causes the difference?How is the cardiac muscle’s refractory period affect its ability to summate and tetanize?Below are the contraction events of the heartplease indicate where the refractory period start and how can you tell?Thank you!
