Why do we use 12 leads for an EKG?
So we can see fewer views of the hearts electrical activity
So we can see more views of the hearts mechanical activity
To provide the MD with different views of the heart's electrical activity
To provide the MD with different views of the heart's mechanical function
An EKG technician is preparing to apply leads to a patient who is scheduled for a 5 lead Holter monitoring. In which of the following locations should the technician apply the ground electrode?
over the fourth intercostal space
left lower abdomen
right lower abdomen
over the manubrium
