The 3rd step of analyzing an Determine the heart rate
ECG is to
a medication that can be used xylocaine
as a local anesthetic as well
as a first line anti-
arrhythmic used to treat
acute life
threatening ventricular
arrhythmia is
Tall and symmetrically increased right atrial pressure and right atrial dilation
peaked P waves may be
seen with
The category of ACE inhibitor
antihypertensive
medications that will cause
vasodilation,
block aldosterone secretion,
and increase urine output
is?
which of the following is the Aortic Arch
first structure that will be
seen when imaging from
the
suprasternal notch?
the wall that separates the interatrial septum
two superior chambers of
the heart is called
the skeleton of the heart Separates the atria from the ventricles
The heart receives most of its coronary arteries
,own blood supply via the
regulation of the heart autonomic
rate speed of electrical
conduction and strength
of
contraction are influenced
by the brain via the ___
nervous system
the cardio accelerator center is part of the sympathetic nervous system
how much blood coming into 70%
the ventricles flows passively
through the aorta?
during which phase of the early diastole
cardiac cycle do the
coronary arteries fill?
Impulses are generated and transmitted when positively
during depolarization
charged ions move inside the cell causing the interior
to become positively charged
the most muscular chamber of left ventricle
the heart
that forces blood through
the aortic valve into the
aorta would be
the t wave is normally oriented in the same direction as the preceding QRS
complex
The initiation of the impulse in P wave
the SA node and its
movement through the atria
produces a:
what is used as a reference isoelectric line
point to identify the
changing electrical impulse
With Lead II, the positive left leg
electrode is positioned on
the
a standardization mark is 10 mm tall; 2 large squares high
, an electrical current points upward
traveling toward a
positive electrode
produces a waveform
that
the most accurate way to 1500 method
measure heart rate is
the electrocardiogram heart's electrical activity
measures
a mini stroke lasting several transient ischemic attack
minutes to a few hours, but
has no permanent damage
The limb leads are obtained right arm, left arm, left leg
by placing electrodes on the
the first heart sound is the tricuspid and mitral
_________________ valve and
the _ closing
the instrinsic firing rate of the 40-60
AV node
What is known as the SA node
pacemaker of the heart?
each large square in the .20
EKG graph paper is equal
to
each small square in the ekg .04
graph paper is equal to
the lead that is grounded RL
Lead III LA to LL
To calculate an irregular heart 6 second method
rhythm use
the electrical impulse that SA node
normally initiates the heart
beat arises from the
cardiac output is equal to stroke volume multiplied by the heart rate
The impulse traveling QRS complex
through the His- Purkinje
system generates a ___ on the
ECG.
