EKG ACQUISITION EVALUATION PAPER ANSWERS
AND QUESTIONS SET A+
✔✔Purkinje Fibers - ✔✔fibers that serve to conduct electrical impulses through the right
and left ventricles causing ventricular depolarization
✔✔Repolarization - ✔✔the relaxation phase of the heart that prepares the heart for
another depolarization
✔✔Septum - ✔✔a dividing wall or partition, such as the one found between the two atria
or between the two ventricles
✔✔Sinoatrial (SA) node - ✔✔a small mass of tissue, located in the right upper atrium,
which serves as the heart's primary pacemaker. depolarization of the SA node produces
a P wave on the EKG and is referred to as the primary pacemaker of the heart
✔✔Tachycardia - ✔✔rapid heart rate
✔✔Deoxygenated blood flows through the... - ✔✔inferior and superior venae cavae to
the right atrium
✔✔From the right atrium, blood pumps through the... - ✔✔atrioventricular (tricuspid)
valve to the right ventricle
✔✔From the right ventricle, blood pumps through the... - ✔✔pulmonary semilunar valve
to the pulmonary arteries, which direct blood to the lungs for oxygenation
✔✔From the lungs, oxygenated blood goes to the... - ✔✔left atrium via the pulmonary
veins
✔✔From the left atrium, blood travels through the... - ✔✔artrioventricular (bicuspid)
valve to the left ventricle
✔✔the left ventricle pumps blood through the... - ✔✔aortic semilunar valve to the aorta
, ✔✔Bicuspid valve is also called... - ✔✔mitral valve
✔✔Standard paper or data standard speed - ✔✔25 mm/second
✔✔What does a wandering baseline look like on an EKG tracing? - ✔✔wavelike up and
down movements throughout the tracing
✔✔What causes a wandering baseline? - ✔✔-movement of the cables or leads during
the reading
-patient movement
-loose electrodes
-dry electrodes
-a patient's labored breathing
-improper skin preparation
-leaving traces or lotion
-oils or gel on the skin
✔✔How do you reduce a wandering baseline? - ✔✔-reposition the limb leads to ensure
they are on fleshy areas
-instruct the patient to make sure the skin is free of topical substances
-clean attachment sites prior to the procedure
-educate the patient on what to expect
-provide clear directions on how to breathe and when not to talk
✔✔What does a somatic tremor look like on an EKG tracing? - ✔✔uneven spikes on the
EKG tracing
✔✔What causes a somatic tremor? - ✔✔-muscle movements
-common causes include shivering
-nervous movements
-Parkinson's
-seizures
✔✔How do you reduce somatic tremors? - ✔✔-shivering: offer a light blanket and
maintain a warm temperature in the room
-nervous movement: explain the procedure thoroughly
-parkinson's disease: placing the palms in a prone position and under the buttocks or
crossed over the abdomen
-seizures: avoid performing an EKG while a patient is having an active seizure unless
otherwise directed by the provider
✔✔What does AC interference look like on an EKG tracing? - ✔✔uniform sharp spikes
on the EKG tracking
