The Conduction Approach to the Heart
1 . What is the path of electrical conduction inside the heart? 2 . Which within ionic conductance (permeability) go with the various phases of the pacemaker potential?
a) In region 1, a decrease in PK and a rise in PNa: In zone two, an increase in PCa b) In zone 1, a decline in PK and an increase in PCa: In sector 2, a rise in PNa c) In zone 3, a huge increase in PNa: In area 4, a rise in PK and a reduction in PCa d) In sector 3, a sizable increase in PCa: In sector 4, an increase in PK and a reduction in PNa e) A and D

1 ) What are you will of ventricular fibrillation? installment payments on your Describe all of the changes in atrial pressure, ventricular pressure, aortic pressure and ventricular amount that arise during the different stages in the cardiac circuit. Illustrate when the various regulators are available or closed.
3. For both of the semilunar regulators to be available:
a) L (pulmonary artery) < P (right ventricle) and P (aorta) > P (left ventricle) b) P (pulmonary artery) < P (right ventricle) and P (aorta) < S (left ventricle) c) L (right ventricle) = L (aorta) and P (left ventricle) sama dengan P (pulmonary artery) d) P (pulmonary artery) > P (right ventricle) and P (aorta) > P (left ventricle) e) S (pulmonary artery) > P (right ventricle) and S (aorta) < P still left ventricle four. During Iso-volumetric contraction from the heart:
a) There is an increase in pressure without a change in amount. b)...
