✔✔The intrinsic rate of the Purkinje network in the ventricles is:
20 to 40 beats per minute.
40 to 60 beats per minute.
60 to 100 beats per minute.
100 to 150 beats per minute. - ✔✔20 to 40 beats per minute.
✔✔What is the heart rate of an ECG with a constant R-R interval of 30mm recorded at a
standard paper speed? - ✔✔50 bpm
RR duration = R-R interval/paper speed
HR=60s / RR duration
30mm / 25mm/s = 1.2s
60s / 1.2 = 50bpm
✔✔Which leads are routinely checked to detect left atrial abnormality?
V1 and V5
V4 through V6
V1 and Lead II
Lead III and AVF - ✔✔V1 and Lead II
✔✔What is a common cause of somatic tremor?
,poor skin prep
muscle movement
wandering baseline
electrical interference - ✔✔muscle movement
✔✔Ventricular tachycardia in which depolarization impulses moving from one ventricle
to the other, resulting in a "twisted ribbon" appearance on the ECG tracing is called
torsades de pointes.
ventricular crossover.
ventricular fibrillation.
ideoventricular acceleration. - ✔✔torsades de pointes.
✔✔An anterior wall myocardial infarction occurs when anterior myocardial tissue
supplied by the _____ artery suffers injury due to lack of blood supply.
right
circumflex
obtuse marginal
left anterior descending - ✔✔left anterior descending
✔✔Which ECG would you expect the doctor to order when the patient has
dextrocardia?
posterior 12 lead ECG
standard 12 lead ECG
right side 12 lead ECG
dextrocardia right side 12 lead ECG - ✔✔right side 12 lead ECG
✔✔P-P intervals in all heart block dysrhythmias are characteristically
absent.
regular.
irregular.
unidentifiable. - ✔✔regular.
✔✔What rhythm has a normal atrial depolarization and a wide QRS complex with QR-
R's pattern?
ventricular fibrillation
sinus rhythm with RBBB
atrial tachycardia with PVCs
sinus tachycardia with LBBB - ✔✔sinus tachycardia with LBBB
✔✔Beta-blockers are avoided in stress testing because they
decrease heart rate:
, increase QRS voltage.
decrease PR intervals.
increase ST depression. - ✔✔decrease heart rate.
✔✔In standard calibration, what are the paper speed and voltage settings?
5 mm/sec, 10 mm/mV

abnormalities on a 12 lead ECG tracing?
ST Elevation in II, III, aVF
tall R wave and ST depression in V1-V2
tall T wave and elevation in leads I and aVL
inverted P wave and elevation in V5 and V6 - ✔✔Tall R wave and ST depression in V1-
V2

HIPPA
wearing PPE
hand hygiene
communication - ✔✔communication
✔✔Which of the following medications is used in the treatment of ventricular
arrhythmias?
digoxin
lidocaine
verapamil
nitroglycerin - ✔✔lidocaine
✔✔Verapamil - ✔✔-calcium channel blocker

that you include a tracing with a V4R electrode, as well. What is the physician MOST
LIKELY looking for by adding this electrode?
dextrocardia
right bundle branch block
right ventricular infarction
