What findings should the technician expect when reviewing the EKG tracing of a
patient who has ventricular hypertrophy?
Give this one a try later!
Increased amplitude of the QRS complex
(A patient who has ventricular hypertrophy has
overdeveloped cardiac muscles)
An EKG technician is repair a patient for a cardiac monitoring and notices that the
patient skin is diaphoretic. What should the technician do?
Give this one a try later!
, Prepare the site with anti-perspirant
An EKG technician notices that waveform on an EKG are very close together and the
patient has unusually rapid heart rate. The tech. should change the paper speed
to________
Give this one a try later!
50 mm/second
(A faster paper speed spreads on the waveforms and makes the tracing
easier to read)
The purkinje fibers serve what purpose?
Give this one a try later!
Carry electrical impulse directly to ventricular muscle tissue
First degree heart block PR interval
Give this one a try later!
Prolonged; greater than 0.20 seconds.
,Located between the left atrium and the left ventricle.
has 2 cusps, also known as the bicuspid valve
Give this one a try later!
Mitral valve
AN EKG technician is preparing a 5-year-old child for a standard 12-lead-EKG. What
actions should the technician take?
Give this one a try later!
Allow the child to apply the electrodes on a doll before the procedure
Abbreviation for Myocardial infarction
Give this one a try later!
M.I.
Which leads record activity of the inferior wall of the left ventricle?
Give this one a try later!
Leads III and AVF
, 5th intercostal space, midaxillary line
Give this one a try later!
V6
Which lead should be placed just below the nipple, in the 5th intercostal space on the
midclavicular line (MCL)?
Give this one a try later!
V4
It should be no more than 0.1 sec. in the limb leads and 0.11 sec in the precordial leads
Give this one a try later!
Normal QRS interval
What modification to lead placement is made for stress testing?
Give this one a try later!
Limb leads placed on patient's torso instead of the limbs
