This course relates electrophysiological principles of EKG com- ponents to heart function. Students identify the individual components of the EKG complex and discuss the best lead placement for a diagnostic EKG versus lead placement for in- tra-procedural monitoring. After identifying rhythm rules, students differentiate between normal and abnormal rhythm strips and paced rhythms, in correlation with known patholo- gies. Students demonstrate the ability to identify heart rhythms and arrhythmias and gain the ability to set up a 12- lead EKG.
