Download Name this dysrhythmia

Name this dysrhythmia:
Idioventricular
(ventricular bradycardia)
An ECG strip shows a rhythm
with normal P-R, P’s are 1:1 with
QRS complexes, rate 70,
rhythm regular, QRS 0.14 sec.
What is the name of the rhythm?
NSR with a bundle
An ECG strip shows wide QRS
complexes at a rate of 170. No P
waves are seen. One possible
interpretation of this rhythm
is V Tach.
What is another possible
interpretation?
SVT with a
bundle branch block
Describe how the marks on the
border of the ECG paper can be
used to determine heart rate.
The marks are 3 seconds apart.
Count the number of complexes
in six seconds and multiply by
ten to find the heart rate.
Name the value of one small
square on ECG paper:
1) In units of time (horizontal)
2) In metric units of length
(vertical)
1) 0.04 Seconds
2) 1 millimeter
Describe the conventional
method of standardization
of an ECG machine
A one millivolt impulse will
cause a deflection of 10 mm
(which is two large squares)
Name three different indications
that PVC’s should be treated
1) Multifocal
2) R on T phenomenon
3) Coupled (or runs of VT)
4) Associated with MI or
ischemia
Where is the primary disease in
patients with first, second, or
third degree block?
The A-V node
Name (in order) the components
of the conduction system
of the heart.
Sino-atrial node
(internodal pathways)
Atrio-ventricular node
Bundle of His
Bundle branches
Purkinje fibers
State in order the numbers used
to determine the heart rate by
counting the large squares
between R waves
(answer counting up to at
least 7 squares)
300-150-100-75-60-50-43-37-33-30
Name this dysrhythmia
Controlled atrial fibrillation
Why is the sinus node normally
in control of the heart?
Because it has the fastest
inherent discharge rate
What are the normal values for:
1) P-R interval
2) QRS duration
1) 0.12 -0.20 seconds
2) Up to 0.10 seconds
Describe the triad of infarction
1) Pathological Q
2) Elevated S-T segment
3) Inverted T wave
