Correct!
Electrocardiographic monitoring is essential role of the CCU staff, who must be adept at rhythm interpretation, lead selection based on infarct location and rhythm [1] as well as lead placement for detection of right ventricular myocardial infarction [2]. Computer algorithms have proved superior to medical personnel for detection of arrhythmias [3]. However, the choice of lead placement and application (ie, skin preparation and use of conducting gels) remain essential human skills.
