EKG Acquisition

The standard speed of 25mm/sec and amplitude of 10mm/mV is represented on the calibration marker at the beginning of a tracing. If the order states to increase the speed to 50mm/sec due to tachycardia, what will happen to the waveform?

• Waveforms are more spaced out and visible

• The change in speed does not effect the waveform

• Waveforms are bunched together

• Waveforms appear upside down

When preparing a patient for an EKG, all of the following must be avoided or removed except?

• Cell phone in pocket

• Use of lotions and oils

• Nail polish

• Jewelry

What is the preferred position for a 12-lead EKG?

• semi-fowlers

• supported supine without pillow

• prone

• standing

Draw the correct placement for the limb electrodes using the appropriate colors: red, green, black, and white

Label Leads I, II and III

Draw & label the augmented views: AVR, AVL and AVF

What is the normal placement for precordial lead V5?

• Right upper chest

• 4th intercostal space, midclavicular line

• 5th intercostal space, anterior axillary line

• 4th intercostal space, right sternal boarder

Where are precordial leads placed for someone who requires a right-sided 12-lead EKG? 

If the patient requires a posterior EKG, where are the electrodes for V7-9 placed?

When viewing Lead I complexes, if all leads are properly attached, should the complexes have a positive or negative deflection?
