hyperkalemia (excess potassium) decreases the resting potential of the cardiac muscle cell. What effect do you think this would have on the force of contraction? You correctly answered: decrease, negative inotropic. 4 Describe the effect that increasing the calcium ions had on the heart in this activity. How well did the results compare with your prediction? Your answer: Increase HR , increase force of contraction. 1 Describe the effect that increasing the potassium ions initially had on the heart in this activity. Relate this to the resting membrane potential of the cardiac muscle cell. How well did the results compare with your prediction? 2 Lab Report Prev 1 of 1 Next PEx Examining the Effects of Various Ions on Heart Rate Reset Activity ALWAYS LEARNING

Your answer: Decrease calcium they block the movement of calcium through the channels throughout all phases of the cardiac AP-decreased calcium causes both decreased rate of depolarization and decreased force of contraction, and decreased peripheral resistance. 3 Lab Report Prev 1 of 1 Next PEx Examining the Effects of Various Ions on Heart Rate Reset Activity ALWAYS LEARNING
