Compare and contrast the molecular events of the action potential in the pacemaker cells of the SA node to those in a ventricular (contractile) cardiomyocyte.
Need help with College level Physiology question – I need a thorough explanation because I need to understand these questions in full please
Compare and contrast the molecular events of the action potential in the pacemaker cells of the SA node to those in a ventricular (contractile) cardiomyocyte. Be sure to point out how these molecular events underlie the differences in shapes of the two types of potentials.
