List the mechanism and give several names of the following: Class I, Class II, Class III, and Class IV antiarrythmics.

The following questions refer to the analysis of cells using flow  cytometry  A) When analyzing cells in a flow cytometer how do you ensure you are analyzing single  cells rather than doublets or clusters of cells and why is that important?  B) How do forward versus side scatter plots enable the characterization of different  types of blood cells in the blood of a patient? How does this relate to a potential  diagnosis of acute leukemia?  C) How do you determine if a patient has B cell versus T cell Leukemia? Why is it  important to know?

A flow cytometer is constructed of many components. For good quantitative results how and how frequently should the various systems be calibrated? What is MESF and how does it apply in flow cytometry?
