How did you do?

OK – let’s get started!!

Monitoring vs Assessing

• Monitoring – EKG leads can be placed

anywhere
– Allows for identification of VF and Asystole

• Assessing – EKG leads MUST be placed in

specific locations
– Allows for interpretation of changes in the

electrical conduction (depolarization and
repolarization changes) i.e., ischemia.
