The P wave of a
normal
electrocardiogram
indicates ______
atrial
depolarization
Which of the
following is not part
of the conduction
system of the heart?
a) AV node
b) Bundle of His
c) AV valve
d) SA node
The second heart
sound is heard
during which phase
of the cardiac cycle?
Isovolumetric
relaxation
What do these intervals represent?
P wave
PR interval
QRS complex
ST segment
T wave
U wave
RR interval
P wave – atrial depolarization
PR interval – time from SA to AV node
QRS complex – ventricular depolarization
ST segment – beginning of ventricular repolarization
T wave – ventricular repolarization
U wave – final component of ventricular repolarization
RR interval – complete time of one cardiac cycle
What is the normal
time span for the
PR interval?
0.12 – 0.20s
In what units is
blood pressure
expressed?
In millimeters of
mercury (mm Hg)
The stroke volume
for a normal
resting heart is
____ mL/beat
70
Define systole and
diastole
Systole is contraction of the muscle
Diastole is relaxation of the muscle
What is ventricular
systole?
Contraction of the
ventricles
What do the sounds
correspond to when
blood pressure is
taken?
The first sounds that are
heard indicate systolic
pressure. When the sounds
stop, diastolic pressure has
been reached
A.
SA node
B.
AV node
C.
D.
E.
AV bundle
Bundle branches
Purkinje fibers
A. normal sinus rhythm
B. junctional rhythm
C. second-degree heart block
D. ventricular fibrillation
Ventricular
tachycardia
First degree heart block
Bradycardia, sinus rhythm
CO = SV x ____
HR
PP = ____ - DBP
SBP
Calculate the mean blood
pressure when systolic blood
pressure is 120 mm Hg and
the diastolic blood pressure
is 80 mm Hg
93 mm Hg
Calculate stroke
volume when pulse
pressure is 50 mm Hg
100 mL/beat
Calculate cardiac output
when stroke volume is 100
mL/beat and heart rate is 68
beats/minute. Convert the
value in liters per minute by
multiplying by 1L/1000 mL
6,800 L/min
Define the terms end
diastolic volume (EDV)
and end systolic volume
(ESV) and relate them to
the calculation of stroke
volume
EDV is the amount of blood
that collects in a ventricular
during diastolic. ESV is the
volume of blood remaining
in a ventricular after it has
contracted. Stroke volume
(mL/beat) equals EDV-ESV
Damage to the _____ is referred to
as a heart block
a)
SA node
b)
AV valves
c)
AV bundle
d)
AV node
d) AV node
When the heart is
beating at a rate of 75
times per minute, the
duration of one cardiac
cycle is _____ second(s)
0.8
Which of the following is the most
important when considering aerobic
exercise?
a) Duration of 20 – 40 minutes
b) Duration of >60 minutes
c)
Intensity
d) Frequency of 3 – 4 times per week
e)
Frequency of 5 – 7 times per week
C) intensity
What is the best way
to look at a P wave?
Lead II
Aortic Aneurysm
(abdominal)
Cardiac Arrest
Hypertension
Shock

of palpitations and, lately, blackouts

Make your wager
What are the 12
leads of the standard
EKG cycle?
3 Bipolar Leads
3 Augmented Leads
6 Precordial (chest) Leads
